Morning all ...
I'm trying to test a null modem cable under FreeBSD by connecting
each end to my two serial ports, and for the life of me, I can't get a
login prompt, so either this isn't possible or I'm doing something
wrong. We ended up testing it by using the 'Direct Connect' feature in
Win98, so we know the cable is working, but I want to get this working
with my FreeBSD machine :(
My /etc/ttys looks like:
ttyd0 "/usr/libexec/getty std.9600" dialup off secure
ttyd1 "/usr/libexec/getty std.9600" dialup on secure
ttyd2 "/usr/libexec/getty std.9600" dialup off secure
ttyd3 "/usr/libexec/getty std.9600" dialup off secure
My kernel/dmesg shows:
sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 16550A
sio1 at port 0x2f8-0x2ff irq 3 on isa0
sio1: type 16550A
And, a kermit session looks like:

Is there something obvious that I'm overlooking here? :(
Thanks ...
