I have been trying to set up Columbia C-Kermit for use under AT&T SVR3.2.1
with one major problem.  When I do a 'set line /dev/tty01' command, the
system hangs completely and I have to reboot.  I think I know what may be
causing the problem:  The device I'm connected to does not implement any
control signals except the transmit and recieve lines (TX and RX in RS-232
jargon).  I believe the hang up may be caused by the lack of a carrier detect
signal being asserted by the remote device.

Is there any way to set up a serial port so that it ignores carrier detect
and other control signals?  The SysAdmin Guide as well as the FAQ for this
newsgroup mention something about 'modem control' ports, but I'm not sure
how to set them up or if they'll solve the problem.

Oh, one other thing: does anyone know where I can get a hold of the FAS driver
that's mentioned in the FAQ? (FTP preferred).  Thanks.
