The basic routine for getting a PCI internal modem working under Linux is as
follows.
1. Make sure it isn't a Winmodem. (I know you said it isn't, but, to put it
plainly, how sure are you?) Best way is to check it against the list at URL
http://www.o2.net/~gromitkc/winmodem.html . Note that some Rockwell-based
modems aren't quite "winmodems" but will work only if error correction is
disabled; the Web page already cited has the details.
2. Figure out what port PnP is assigning it to. (COM1=/dev/ttyS0,
COM2=/dev/ttyS1, COM3=/dev/ttyS2, COM4=/dev/ttyS3 .) See the PnP HowTo (at
http://metalab.unc.edu/LDP/HOWTO/Plug-and-Play-HOWTO.html) for details --
there are too many different ways to do this for me to guide you here.
3. Make sure there isn't an interrupt conflict. If the modem is on S0 or S2,
check for anything else using IRQ 4. If on S1 or S3, check IRQ 3. To check,
enter "more /proc/interrupts" and look for an entry for the appropriate IRQ.
Possible conflicts can be your mouse or, in some cases, your NIC (Ethernet
card).
4. Symlink /dev/modem to the appropriate actual dev. E.g., "ln -s /dev/ttyS0
/dev/modem".
5. Use setserial to probe /dev/modem ("setserial /dev/modem"). See if it
returns a UART type. If it does, its' found a modem (more exactly, it's
found a serial port, but if you have the right dev, that means it's found
the modem).
If this gets you to a working system, then great. If not, a follow-up
posting with the details of how far you got in this sequence before
encountering trouble may let me or someone else on the list offer a specific
suggestion.
