Most motherboards have 2 built in uart's on com1 irq 4 and com2 irq3.
If you have anything connected to either of these (a mouse, say), it
_will_ conflict with what you set your modem for, either the ioport, or
the interrupt. If you're sure you're not using the builtin serial
ports, or don't have builtin ports, you must still override the default
IRQ for com1:
setserial /dev/ttyS0 irq 3 [spd_vhi]
If it responds
/dev/ttyS0, UART: 16550A,...
or similar, things are looking good.
May as well set up /dev/modem:
rm -f /dev/modem
ln -s /dev/ttyS0 /dev/modem
If you see reason and change your jumpers, you will need to adjust
those commands.
May as well try minicom. As root, run
minicom -s
Select serial port setup. check that A: serial device is either
/dev/ttyS0
or /dev/modem, if not, change it. Exit from setup. It houuld show a
box, "initializing modem", then the AT commands it sent the modem, and
on the next line,
OK
if so, you have set up your modem.
If you have got this far, you will want to put the setserial command in
your startup files (that's the only bit of this that needs to get done
each time you boot), but you didn't tell us what distro you're using,
or much else, I'm thinking, and it's easier if we know that. It's not
hard, but it's another topic. Enough for now.
