Hi again! I've got another problem with my Linux setup (SLS 0.98.5). I have
the second serial port (COM2 or /dev/ttys1) connected to my modem and the
third (COM3 or /dev/ttys2) to another PC via a null modem cable. I have
neither been able to connect to the modem into Linux nor does the null modem
give me any access.
I am using Qmodem under DOS on the other PC (386/40), and if I set the baud
rate to, say, 9600, and run "getty 9600 /dev/ttys2 &", for example, I get the
login message on the other PC just fine, but that's it then. No reaction
whatsoever to any characters I send to Linux from the other machine.
I have tried various options ("-h", or "-m" with the modem), several baud
speeds from 2400 to 9600 and several different setups of handshake and comms
parameters on the second machine, to no avail. What am I doing wrong?
Any help greatly appreciated!
Cheers -- Hartmut
