Check the man page for setserial, and run setserial to test the modem.
# man setserial
If it shows a 16550 uart at com2 irq5 you are on the way.
After installing the uucp rpm, try talking to the modem on COM2:
# cu -l /dev/cua1 See if you can send AT and get an OK back.
Type <return>~. (return tide period) to exit cu. Or try minicom and
maxicom. I like cu because it needs no setup.
*************I did a setserial on /dev/cua1 and I got:
UART 16550A, Port: 0x02f8, IRQ: 3
Since I had already installed the uucp rpm, at this point I went ahead and
did a # cu -l /dev/cua1 What I got back was:
cu: /dev/cua1: Line in use.
I don't understand why it says IRQ 3 when I physicaly changed it on the
card via the jumpers. Well, I DO understand that that is the default IRQ
for that port but I guess I was hoping that it would probe the card somehow
and realise that it was suposed to use IRQ 5. Is there a way to change
this in Linux? Besides that, what does "Line in use" mean exactly?
Thank you for the help. I do feel like I am geting somewhere but my boss
is NOT happy with my progress. He wants it done yesterday. Is that what
they teach bosses in boss school? :) Face it: No amount of presure on me
is going to get it done before it's done.
Thanks again.
