- Hardware hand shaking can be a problem, but there is a signalling method
- in a sense, empoyable. set the modems dsr to follow the recieved data,
- and have dsr connected to dcd on the 5-pin. Kermit, and others, use
- dcd as a dsr signal ... which implies data incoming, and set about
- recording the incoming into a buffer, to process when the burst stops.
- because there is no cts, or rts, (or real dcd) there can be problems with
- continuous data, but a good terminal/transfer program can handle it.
- See below for the ftp'able (try mail ftp ! ) terminal programs !.

- Myth .. all myth .... I use v42bis 9600 bps connections all the time with
-
- my //c. So it can be done ... I'll give a list of software I've tried.
- Most shareware, some are public domain. Kermit is widely available,
- and reccomended as it never hangs, crashes, and always available
- or kermit transfers. AGATE recommended for high speed transfers.
- (Agate handles 1k packets, and 20k disk accesses.and also falls back to
- smaller packets, very nice :) ) I should pay its shareware fee. Do you
- people accept Aussie dollars ?
-
- KERMIT : best vt100, good for unix, but keypad/function keys i havent worked
- out pagination is neccasary, even ls loses characters at that speed
- buts that common for all speeds above 4800 ...
- 19200 max, but kermit file transfer is always slow.
- PACKET size is FA (thats in hex :) )
- cntrl-g is annoying as a buzz, due to interrupts.
- Zlink. : 9600 (higher doesnt work).
- Xmodem useful. .. Zmodem would be better :)
- : terminal emulation good, vt220 keys useful..
- AGATE : 9600 only (only goes to 14400). Zmodem :) (receive only :( ),
- crashes whilst emulating vt100, apparently only on //c's :(
- Talkischeap : Works ok. 4800 maximum. Apparently set up to handle all sorts
- : of terminals, but doesnt quite manage compatibility with
- : the BSD 5 I connect to ...Could not work the file transfer.
- : file transfer is ymodem or kermit ?
- DCOM (dont remember full name) : large number of graphics cards, serial cards,
- modem command sets, (large for an apple 2 ) , no baud control :(
- no file transfer ? :( , no emulation , or is it vt100 and my adversion
- to reading manuals leaves me ignorant of its capabilities ?
-
- Comm.system : no emulation, couldnt work file transfer. 4800 max ?
-
- ATP : havn't unpacked it yet. executioner is such a pain, compared
- to binscii/shrinkit (I hadnt found stripexec yet !! )
-
-
-
- Are there any more ? I want to have a look at them all,
- I'm not interested in mainstream commercial ones, I am in a country town !
- in OZ ! :)
