[comp.sys.atari.8bit] communications on an Atari 800

jhs@MITRE-BEDFORD.ARPA (02/14/88)

As usual, the net subscribers have provided a good survey of the available
options.  My comments don't add much, but maybe will help to confirm some of
the impressions you have received from other mailings.

The 800 can be used as a vt100 terminal quite successfully.  The Atari 850
interface and the ICD P:R:Connection are the most widely accepted choices
for interfacing to an RS-232C device.  The serial bus in the Atari is a TTL
bus, so needs TTL to RS-232C level converters to run a normal modem.  Also,
the "handshake" signals would be absent, but you could do a trick like using
the cassette motor control line to signal DTR or something.  There is a device
called the R:Verter that used the serial bus in this way.  I don't know if it
is available any more.  The 850 is hard to find.  This leaves the
P:R:Connection as the best choice, unless you want to hack together an
interface or buy one of the Atari modems with built-in interface.

As for terminal emulators, the clear choice, given your requirements, is
CDY's OmniCom.  This does a pretty good vt100 emulation (the adjective
"halfhearted" that someone used doesn't seem to me to be justified -- it
handles the graphics and cursor commands from my screen editor just fine),
and also supports kermit, xmodem, and ascii transfer.  Ascii transfer can go
to a file or to the printer if you wish.  Also there is an instantaneous
"print screen" function that is very handy.

John Dunning's kermit65 is a very good choice for vt100 emulation, but at last
report lacked some of the features you specifically mentioned.  It also lacks
macro key definitions, and so far as I know this means you have to do any
keypad operations as sequences of three or so keystrokes.  Dunning will, I am
sure, fix all this one of these days, but right now OmniCom is really what
you need.  It's available as a "shareware" program, which means copies of it
are available free, but the author requests a contribution if you wish to keep
on using it permanently.  I have a copy which I'll be glad to send if you
wish.
