I set up our USB pda with /dev/ttyUSB) and 1.  BL does not do devfs, which 
is a different system.  For a modem you would probably want /dev/ttyACM0

I used the same software with serial and USB modems except for making the 
USB devices and insmodding usb_serial.o, which will not insmod in kernel 
2.4.31 but will in 2.2.26.  I posted to the list how to do USB pda.

We have two XT boards with 9 16-bit ISA slots each.  ANd some Pentium I's 
with 3 or 4 ISA slots.  The 1.2GHz has only 1.

Your PCI slots are half-height.

Is there a USB serial port?

We were just given a full-height PCI serial card but hope never to need 
it.  It came with Windows drivers.

Wish me luck with wireless pcmcia.
