============================================================================


1) What do I need to connect to the Internet?

   First, you need a service provider.  These come essentially in two
   flavours; those providing direct IP access, and those providing access
   to a machine they have on the Internet.  Second, you need the relevant
   software.  The software you need depends on the type of service
   provider.

   To elaborate, service providers like Demon Internet Services provide
   dial-up access to low-level Internet.  This means that your machine is
   actually a machine on the Internet, albeit intermittently.  To
   use this kind of service you need to run complex software on your
   machine (known as TCP/IP software).  You cannot use simple comms
   software (Arcterm, Hearsay etc) to use this kind of service.  You can
   use any facilities of the Internet for which you have the relevant
   software.

   Services like CIX (Compulink Information eXchange) provide a facility
   whereby their machine runs the TCP/IP software, and you get an account
   on their machine.  Essentially this means that your machine is used
   as a terminal onto their machine.  For this kind of service, you use
   normal comms software (Arcterm, Hearsay etc).  You can only run the
   facilities that are available on the service provider's machine.

   Increasingly, bulletin boards are providing "gateways" to the Internet,
   usually for EMail and Network News (also known as Usenet).  This is a
   much more limited form of Internet access, but is much cheaper for
   the user.

----------------------------------------------------------------------------


2) Who can supply direct IP access?

   At the moment there appears to be an explosion in the number of service
   providers for the individual user.  BT and the BBC for example are hoping
   to provide this kind of service.  However, services that are available
   now include (I have limited this list to those providers who have
   subscribers using Acorn machines):

   a) Demon Internet Services (UK)

      A UK-wide provider, cheap and effective.  Mail internet@demon.net for
      information.  Or download ftp.demon.co.uk:/pub/doc/Demon.txt.  Points
      of presence in many areas, supplying local-call access to a large
      number of subscribers.  Tel: (081) 349 0063
      Support available in the newsgroup demon.ip.support.archimedes.

   b) Stichting Knoware (NL)

      Supplies service to the Netherlands.  Email to knoware@knoware.nl for
      information.  !TCPIP works with this service, as does !ReadNews.
      Michiel Koolen (mkoolen@trickbox.knoware.nl) runs their Archimedes
      support.


   There are a couple of lists available that are more comprehensive; a list
   of UK providers can be found via ftp from ftp.demon.co.uk as
   /pub/archives/uk-internet-list/inetuk.lng.  There is an international
   list distributed from  - send email with
   "Send PDIAL" as the text body to get the latest version.


   *** Please send in any not listed here that have subscribers ***
   *** using Acorn systems.  Include any information concerning ***
   *** setting up that would be of use to new users.            ***

----------------------------------------------------------------------------


3) Who can supply indirect access?

   There are many of these.  They can usually be used with normal comms
   software, eg. Arcterm, Hearsay etc.

   a) CIX - Compulink Information eXchange

      A London-based conferencing system, also providing email, ftp, telnet,
      irc, gopher, www etc.  Email: cixadmin@cix.compulink.co.uk,
      Tel: 081 390 8446.  Join conference "archimedes" or "bbc" to find
      other Acorn users.

   b) Compuserve

      A large international conferencing system (albeit with a heavy US
       bias).  Currently provides an EMail interface and access to the Usenet
      News (GO INTERNET).  More comprehensive internet access is planned,
      probably before the end of the year.  Forum UKCOMP topic Acorn/Z88 is
      the place to find other Acorn users.
      Tel: London (081) 801 2001, Birmingham (021) 632 4858,
           Reading (0734) 391 064 or 569 025, Bristol (0272) 255 111

   c) Many bulletin boards provide EMail and limited newsgroup access;
      among the more popular Archimedes boards are Arcade (0181 654 2212
      24hrs most speeds), The Digital Databank (0707) 329306 24hrs most
      speeds) and The World Of Cryton (0749 670030 24hrs most speeds).
      These also hold lists of other Acorn-relevant bulletin boards.

----------------------------------------------------------------------------


4) What software do I need for direct access services?

   There are several options.  Under RISC OS, there is !TCPIP, also known as
   KA9Q (the call-sign of the radio ham who first wrote it for the PC), and
   Acorn's TCP/IP Suite, although you need a suitable driver for dial-up use
   (Gnome Software market a SLIP driver).  Most software that makes use of
   the serial port will need !SerialDev, the serial device drivers.  These
   are written by Hugo Fiennes (altman@cryton.demon.co.uk) and are available
   from most sources of Acorn software.

   Under RISCiX, everything you need should already be there.  You should
   find that most UNIX sofware compiles without too much trouble (see
   below).  Running X-Windows (and hence graphical WWW clients like
   X-Mosaic) is possible, if a little slow.


4.1) Issues relating to !TCPIP - the port of KA9Q

   a) Where can I find it?

   Latest versions of the software can be found via ftp from ftp.demon.co.uk
   in /pub/archimedes.  Other popular sites that carry copies include Hensa
   (micros.hensa.ac.uk), Stuttgart (ftp.uni-stuttgart.de).  Can also be
   found on Compuserve (GO UKCOMP), and bulletin boards (eg. Arcade, The
   Digital Databank).  You will also need dialling software; this can be
   your normal comms software, but dedicated diallers are better - !Slipdial
   and !Calldemon are available from the same sources as above.

   b) Who develops/developed it?

   Currently maintained by Anthony Frost (vulch@kernow.demon.co.uk, G8UDV)
   and Adam Goodfellow (email to tcpip2@comptech.demon.co.uk for
   TCPIP-related stuff).
   Original software for DOS by Phil Karn (KA9Q), first ported to the
   Archimedes by Jonathan Naylor (G4KLX).

   c) Does it work on the Risc PC?

   As of version 2.01, it works well.

   d) News is taking ages - how can I speed it up?

   This often happens if you don't connect for a week - the retrieval of
   messages over a day or two old seems to take forever.  The solution is
   to edit the "DemLast" file to a more recent date.  The problem will
   probably vary in severity depending on the speed of (and load on) your
   local news server.  The DemLast file is found inside ...!TCPIP.nntp
   on versions of !TCPIP up to 2.00f, from 2.01 onwards it is found
   in !TCPIPUser.NNTP.

   e) !TCPIP (KA9Q) crashes with "Bad Memory Access".

   Several possible causes,
   i)   long lines in the "DemGroup" file - split into two or more lines.
   ii)  Forgetting to surroung numeric addresses with square brackets -
        use "[127.0.0.1]" not "127.0.0.1".  From version 2.01 this is not
        a problem - both forms of address are accepted.
   iii) "DemHist" file over ~20K.  Quick solution is to delete the file,
        the problem will then go away (until DemHist grows too big again!)
        DemHist should be "trimmed" regularly, by deleting some lines
        from the beginning of the file (it doesn't matter how many, as
        long as you delete whole lines and the resulting file is
        a fair bit under 20K).
        The best way to do this is to use the likes of !SlipDial, which
        can automatically trim the file each time you connect.
        This should also not be a problem from version 2.01 onwards,
        although it is still a good idea to trim the DemHist file regularly
        for speed.

   f) !TCPIP (KA9Q) can't find a site.

   If the machine that "resolve" uses to resolve hostnames is down, then
   the site will not be found.  Unfortunately, this information is "cached",
   i.e. the resolver remembers that the site is unavailable and next time
   you can't get to it even if the resolve server is back up.  Type
   "resolve purge" to clear the cache, and try again.

   Resolve as implemented in !TCPIP currently can only resolve one hostname
   at a time - if a second request is made before the first is completed then
   the site comes back as unknown.  This has the same effect on the resolve
   cache as above; solution is to type "resolve purge" in the same way.

   e) How do I configure !TCPIP (KA9Q) for setups other than Demon?

   Knoware works with a similar setup to Demon's - contact Michiel Koolen
   for details (mkoolen@trickbox.knoware.nl).

   The main differences on other systems are the connection sequence (for
   which a suitable !SlipDial script is required) and the host names of
   the relevant mail and news servers.


4.2) Issues relating to the TCPIP suite (Acorn)

   Contains a good VT220 emulation, and a basic TCP/IP stack.  Does not
   provide SMTP (email) or NNTP (network news) at the moment.  The suite
   provides a Berkeley socket look-alike interface, which should enable
   software to be ported without too much difficulty, however I am unaware
   of any such available software.

   A SLIP driver (IP-SLIP) is available fromn Gnome Computers, Cambridge,
   which is needed for dial-up connections.  Gnome can also supply a
   DOMAIN module which provides domain-name lookup.


4.3) Issues relating to RiscIX and the TCP/IP stack.

   As said above, this is not a problem for those who know UNIX.
   Some things worth noting, however.  Get the kernel kit from Acorn or
   Granada MicroCare, and build a kernel with PPP support built-in, then
   compile PPPD.  Use ifconfig etc. to configure the routeing.  This is too
   complex a process to describe in detail here, and you should only do this
   sort of thing if you know what you are doing anyway!  There is also a
   "BIND" patch, which reduces dependency on the local hosts databases.

   Granada MicroCare are on Harrogate (0423) 525412.

----------------------------------------------------------------------------


5) What software do I need for indirect access?

   All that is needed here is normal comms software, like !Arcterm 7 from
   The Serial Port and !Hearsay from Beebug.  Both are perfectly competent;
   both have many satisfied users.  There is a little public domain
   software, !ZAnsi includes ZModem file transfer which is the most
   efficient commonly used transfer protocol in the BBS world.

   As with indirect access, message reading and composing can usually be
   done on-line; however this can get expensive as you end up spending a lot
   of money on your 'phone bill.  To alleviate this problem, OLRs (Off-Line
   Readers) are available.  !ReaderS from Anthony Frost supports several
   BBS formats, including those used by most Acorn-related bulletin boards.
   For CompuServe, a package is available from Richard Proctor called
   !Arctic.  See below for further information.

   Arcterm 7 and Hearsay both provide scripting facilities which allow
   automation of sessions.  Scripts are available for several bulletin
   boards, and also for CIX.

----------------------------------------------------------------------------


6) What newsreaders are there for the Acorn range?

   There are no commercial newsreaders (yet).  However there are several
   PD and Shareware/Careware newsreaders around.  A few months ago there
   were only two real contenders here (!ReadNews and !ReaderS), but all of
   a sudden we are spoilt for choice!  I could say something about public
   transport and buses here...
   
   In an attempt at not appearing biased, I have listed them in alphabetic
   order.  I hope that any comments I have made are fair - people get very
   touchy about their favourite newsreader, source of many a flame war!.


   a) !Arctic

      This is dedicated to CompuServe, currently supports conference
      messaging, mail, and file transfers amongst other things.  Available
      from the UKCOMP forum (Acorn/Z88 topic) and from good bulletin boards.
      It is shareware, registration currently costs 10 UKP.  It automates
      reading, posting, file upload and downloads amongst other things.  For
      further information contact Richard Proctor on Compuserve (user ID
      100031.604) or as rjp@waveney.demon.co.uk on the Internet.

      Current hints:

        None really.  Make sure you have the latest version (currently 2.43)
        as Compuserve have recently upgraded their system.  Note that it
        only works with Compuserve at the moment.


   b) !EasyMail
   
      A newcomer to the scene, this news/email reader also handles message
      downloads from BBS systems running ArcBBS (including Arcade, The
      Digital Databank and The World of Cryton).  Written by Marc L.Veary,
      marc@mlveary.demon.co.uk.


   c) !News

      This has only recently appeared on ftp.demon.co.uk in /pub/archimedes.
      Haven't had time to try it out yet...
      Written by Timothy Kimber (ceetnk@caledonia.hw.ac.uk term time,
         tim@mobius.demon.co.uk other times)


   d) !News-o-saurus

      This is a single-tasking newsreader (i.e. doesn't use any nice
      windows!) and needs a large amount of RAM (2Mb+), as it is written
      in Perl.
      However, it doesn't crash, and handles threads very well.  Similar
      in style to "rn" et. al. on UNIX systems.
      In my opinion it has the best threading capability of the available
      newsreaders that I've seen.
      Written by Martin Portman (martin@tumble.demon.co.uk).
      "Freeware".

      Current hints:

        None really.  Does what it does without much difficulty.  If it fails
        to run, this is invariably due to lack of memory.  Increase the
        wimpslot (edit the !Run file) and try again.


   e) !ReaderS

      This is a general-purpose reader that caters for Bulletin Boards
      as well as interfacing with !TCPIP.  It provides good navigation
      of threads, but doesn't follow this through when posting messages.
      Also a little unstable for Internet access at the time of writing.
      Easy to set up.  Good option if you already use it for BBS use.
      Written by Anthony Frost (vulch@kernow.demon.co.uk).
      "Careware".

      Current hints:

        a) !ReaderS locks up when I try to start it

           The !MailDir application MUST have been seen by the filer
           before !ReaderS is used for News and Email.  !MailDir is the
           repository for incoming and outgoing mail with !TCPIP (KA9Q).
           As of version 2.01 of !TCPIP, a new application !TCPIPUser
           replaces !MailDir, and in this case !TCPIPUser must be seen
           by the filer.

        b) When !ReaderS crashes, just try again.  The only reliable way to
           get !ReaderS working when it repeatedly crashes is to delete the
           message database (unfortunately).  Delete the file "DemMail" from
           the !ReadBack application.


   f) !ReadNews

      A competent newsreader.  Many facilities; easy to add your own.
      Unfortunately suffers from a limit of 77 article per newsgroup,
      and doesn't provide any neat threading facilities.  A little daunting
      to set up initially as it was written to interface with !RUCP, not
      !TCPIP.  Read the help files supplied with (at least) the versions
      on ftp.demon.co.uk for step-by-step instructions.
      New version (0.31) imminent, which will solve the 77-arcticle limit,
      the spurious CTRL-A that appears between postings and the signature,
      and it should also simplify the setting up procedure.
      Written by Julian Wright (jwright@comp.vuw.ac.nz)
      "Freeware".

      Current hints:

        1) To solve the CTRL-A problem (see above), select
           Options->Signature->Script from the main menu.

        2) Article limit.  No real reliable solution here (that I know of)
           You can try using the likes of !Memphis to support more than
           77 files in the News subdirectory structure, but this is slow
           and unreliable.

        3) Having trouble setting up?

           a) You need to set up !RUCP - however only bits of it are
              relevant.  The files you need are !Boot, !Run, Passwd,
              SystemRC, Systems, the directory trees UserHome and uucp.
              In the "Systems" file, the actual details are ignored by
              !ReadNews, the important thing is to write one line for
              "news" and one for "post" on a Demon setup, so that !ReadNews
              knows about the NNTP server and mail server respectively.
              In the "SystemRC" file, set "MailServ=post", leave the rest
              alone.  In the "!Boot" file, set RUCP$NodeName to your node
              name (the first word in your hostname, for example my hostname
              is banana.demon.co.uk, so my node name is banana).  Set
              RUCP$Domain to the domain name (in my case demon.co.uk) and
              RUCP$User to your normal username.  That should complete
              the setting up required for !Rucp.

           b) With the latest version of !Incorp, the debatcher that goes
              with !ReadNews no longer needs the filters needed for previous
              versions.  However to work properly with !TCPIP (KA9Q)  you
              need to ensure that the mail separator is ^A - to do this
              change the "Config" file in !TCPIP so that it reads:

                  smtp separator ^A

              Although "smtp separator rnews" would be quicker, it fails
              because !TCPIP (KA9Q) adds an extra line between mail messages
              for some reason.  Future versions of either !TCPIP or !Incorp
              may cure this, which would speed up debatching considerably.
              The default setup of !TCPIP (KA9Q) comes configured with
              "smtp separator from", which causes the machine to crash
              needing a CTRL-Break when used with !Incorp.

           c) !ReadNews itself is simple, just copy it along with !Incorp
              into your internet directory.


   g) !TTFN and !NewsBase

      Together these form an excellent pair.  TTFN is a news/email reader,
      NewsBase is a news database thingy.  TTFN looks somewhat like
      !ReadNews, but is far superior.  A lot of effort appears to have been
      made to make them easy to configure, automatically picking information
      up from !TCPIP (KA9Q).
      Currently !NewsBase only supports !TCPIP (KA9Q).  !TTFN supports
      whatever !NewsBase supports.
      Latest versions available from ftp.demon.co.uk in the Archimedes
      section.
      TTFN written by Robert Orwin (ttfn@wong.demon.co.uk)
      Newsbase written by Graham Allan (allan@mnhep1.hep.umn.edu)

      Current hints:
      
        None, really.  A newcomer to the scene, no time do develop serious
        problems, and setting up really is a doddle.


----------------------------------------------------------------------------


7) Can I use WWW, Gopher etc. on my Acorn?

   There is now a Gopher client, written by Anthony Frost, available for
   ftp from ftp.demon.co.uk which interfaces with !TCPIP (KA9Q) v2.01.
   Well done Anthony.  The gopher client allows access to Veronica, which
   is a search utility linked to gopher.
   
   And now there is also a Web client!  ArcWeb, written by Stewart Brodie
   is available from ftp.demon.co.uk /pub/archimedes/www.  Currently
   lacking "Forms", but this is on the way.  Other products are on their
   way - Doggysoft are hoping that !Termite will support WWW etc. fairly
   soon.

   There are also public access clients available via TELNET which
   provide access to the facilities without the need for local
   client software.  There is a trade off in speed and often
   functionality, but it's better than nothing.  For most of these
   types of facility you need a telnet client capable of supporting
   VT100 terminal emulation (or above).  !TCPIP (KA9Q) supports this, as
   does Acorn's TCP/IP suite, which includes a VT220 emulator.

   Here is a list of sites for various facilities:
   *** I'd like to list other facilities, please make suggestions, ***
   *** If you know of any other public access sites, please let    ***
   *** me know - it's a bit unfair to direct everyone to the same  ***
   *** place if there is more than one!                            ***

   a) WWW (World Wide Web)
      The following public-access Lynx clients are available (Lynx is a text
      based WWW browser; no pictures and sound but it's better than nothing):
          telnet www.tecc.co.uk 9001        (The "9001" is very important)
          telnet www.info.cern.ch

   b) Gopher
      If you don't use !TCPIP (KA9Q), for which there is a client availabe
      via ftp from ftp.demon.co.uk, the following  Public-access gopher
      clients are available via telnet:
          telnet gopher.brad.ac.uk
          telnet panda.uiowa.edu
          
      You can also access gopher through the World Wide Web.  In other
      words you can get at it via public-access Lynx clients (see (a)
      above).  Press "g" to perform a "goto", then type in:

          gopher://
                    

   c) IRC
      telnet to irc.demon.co.uk, for a public access IRC client.  Be
      prepared to be on-line for a long time...


   As far as indirect access is concerned, the above public access
   clients are of course still available to those services supplying
   telnet access.  CIX supplies its own facilties for the above,
   again running text-only versions for VT100-capable terminals.

----------------------------------------------------------------------------


8) Serial ports, transfer rates and other mysteries.

   a) Serial ports and SerialDev.

   The various different models of Acorn Archimedes et. seq. computers have
   different capabilities with respect to their in-built serial ports.  The
   older machines often have difficulty above 9600bps.  There are two
   modules available via ftp from ftp.acorn.co.uk in /pub/riscos/patches
   which alleviate problems (Risc OS 3.11 does not need these as they are
   already on ROM).  This should enable reliable communication at 9600bps
   and possibly at 19.2Kbps
   The other solution is to purchase one of the serial port cards available.
   These give high-speed capability, and recoup their cost rapidly.  Go for
   one that can support 115200bps - this may seem excessive but the V34
   standard has now been ratified which gives a modem-modem speed
   of 28800bps; with V42bis compression this can theoretically come though
   to the computer at up to 4x28800=115200bps.

   In order to assist software to communicate with the various serial port
   systems, Hugo Fiennes developed the "Serial Block Drivers", which are
   needed for most comms software.  They are available as an application
   called !SerialDev from most sources.

   b) Transfer rates.

   With a 14.4Kbps V32bis modem, you should be able to get up to 1400 bytes
   per second when transferring binary files (i.e. files that are compressed)
   with FTP, and up to 2500 bytes per second and above when transferring
   text files.  Note however that transfer rates also depend on the speed of
   the route between your service provider and the machine at the other end.
   Often this can reduce flow considerably.
   In this case, find out if your service provider supplies a "BatchFTP"
   service, where you can send mail to one of their machines which will then
   transfer the required file to their own machine, from which you can
   download the file at full speed later on.  Both Demon and CIX supply this
   service at no extra charge.

   c) UUencoding, Tar, Zip etc.

   When a binary file is sent over the Network News system, it has to be
   coded in ASCII as the news system does not generally support 8-bit
   transfer.  In this case the most common form of encoding is called
   "UUEncoding".  The results are distinguishable by long files of gibberish
   where the first letter of each line is "M".  To decode these files, you
   need "UUDecode", a version of which is available from all the usual
   places.

   If a file is very long, it is often split into several parts.  To decode
   these files, they need to be recombined before decoding.  Often, due to
   the way the news system operates, the parts can become jumbled.  They
   should be labelled "part 2 of 3" etc to enable reliable recombination.
   There are several utilities which can do this for you automatically; for
   example !UUExplode, which is available from the usual sources.  This
   enables you to double-click on a file of type UUEncode (7FE) and watch it
   explode into the decoded files automatically.  Some newsreaders will
   cope with this, automatically glueing multi-part uuencoded files together
   for easy decode (the only available one that does at the moment is
   !ReadNews).

   Once you have the decoded file, it will often be an archive of some sort,
   probably compressed.  Most software repositories which deal with
   Archimedes software use "!Spark" from David Pilling to archive and
   compress the software.  !SparkPlug is available in the public domain to
   decompress such archives.  The other utility commonly used is !ArcFS, as
   used by the various Acorn magazines for their cover discs.  This is
   read-only; !ArcFSR/W is the read/write version, and is available
   commercially from most outlets.

   In the PC world, the most common utility is "PKZIP", these files can be
   noted by their ".zip" suffix.  !SparkFS supports the PKZIP format.  And
   of course you could use PKZIP itself with a PC Emulator if you have one.

   In the UNIX world, a combination of "tar" and "compress" are used,
   versions of which are available for the Archimedes.  "tar" takes a set of
   files and combines them into one file, and "compress" compresses files.
   Usually such "tarchives" are noticeable by the ".tar.Z" suffix.
   Sometimes "GNUZip" is used instead of "compress", in which case the
   suffix is ".tar.gz".  A port of GNUZip is also available from the usual
   sources.
   
   SparkFS from David Pilling also handles uuencoded and ".tar.Z" stuff.
   However it doesn't cope with multi-part uuencoded postings if they
   arrive out of order.  As far as ".tar" and ".Z" are concerned it is
   complete.

9) Use of TCP/IP over packet radio.

   !TCPIP (KA9Q) is well suited to running TCP/IP over packet radio; after
   all that is what it was written for in the first place.  However there
   are strict (global) regulations regarding what can and cannot be
   transmitted over the amateur bands.  This technically outlaws copying
   stuff to and from the Internet without taking care to vet all material.
