I just went out and bought a brand new, fully hardware PCI modem (for $68!), USR 56K V.90 w/ Voice (2976/3298). Unfortunately, it does not seem to get assigned a ttyS* port during the boot process. The Modem HOWTO gives some tips for finding out the essential information, then says without giving specific directions, to use that info with setserial to assign a serial port to the hardware. However I am at a loss as to how to actually do that. Here are the relevant results of what I have tried so far. Any advice, or pointers to more detailed instructions?
In the BIOS, PnP OS is OFF.
Using pppconfig and setting the device to any of /dev/ttyS*, then pon, gives "No dial tone" results in plog. Output of wvdialconf are at the bottom of the info below.
# dmesg | grep tty
# dmesg | grep modem

Also this information from http://hazard.com/linux/pci.html:
You just plug in the card, start the computer and enter the command
*lspci -v*
The output will list all your PCI devices, and should have a section like this:
00:0c.0 Serial controller: US Robotics: Unknown device 1008 (rev01) (prog-if 02)
Subsystem: Unknown device 12b9:00ad
Flags: medium devsel, IRQ 10
I/O ports at e800
Capabilities: [dc] Power Management version 2
It would be helpful if the manufacturer would fill in the device fields, but if there's any confusion just run the lspci -v command before and after you insert the card and look for the new device id. You just note the IRQ (10 in this case) and the I/O port address (0xe800 in this case, you have to add 0x to the beginning to tell setserial it is a hexadecimal value).
Then, (using the IRQ and port you noted above), give the command
*setserial /dev/ttyS3 port 0xe800 irq 10 uart 16550A*
