  That bit me a couple of times.  Long story short... the *DEFAULT* in
the kernel is to only support 4 serial ports (COM1: through COM4: in
DOS-speak).  To support more than 4, which is required for PCI modems,
USB modems, etc, you have to build in support in the kernel...

  Do you understand "make menuconfig" (I hope)?

- Device Drivers  --->
- Character devices  --->
- Serial drivers  --->
- (6)   Maximum number of 8250/16550 serial ports
- (5)   Number of 8250/16550 serial ports to register at runtime

  Works for me with a PCI modem.
