Subject: Re: IS there an IBM PC version of modem - (nf)

I know this has circulated before, but since there is another
question about it--

I have used PC-Talk Version 3 on an IBM PC under PC-DOS to 
transfer files with CP/M machines running MODEM7.
PC-Talk supports the MODEM7/XMODEM/Christenson (sp?)
protocol for single file transfer, but not batch
transfer.  It has worked fine for me at 9600 baud.
PC-Talk is "freeware", which means you can copy and distribute
it for free, but the author would appreciate your sending him
$35 if you like it. If you do this, you will get updates
in the future.  I got my copy for free from the local
IBM PC users group.

If you want to transfer to the IBM running CP/M-86, that's
another matter, which I have not yet confronted.
However, I did bring up "cmodem.c" (from the SIMTEL archives)
on a Zenith Z-100 running ZDOS (MS-DOS) and the Lattice C
compiler. Presumably you could get it to run under CP/M-86
by using the DRI C compiler or another one.

Good luck. If you need more info, contact me.
