My system already had one serial port, ttyS0 which is working.
I've installed a Dynamode 2-port serial card and the kernel sees the two
ports. This provides two ports is:
PCI Spec Revision 2 compliant
Compatible with 16C550 UART
and says that it supports Linux.
However, I can't use them. I've tried using both minicom and faxxaddmodem
setting up a Hylafax modem bank).
Can anyone suggest what I need to do please.
Explain what actually happened when you tried it. Also check the cables
and the like are right (I'm guessing you've tried the same modem/cable on

Thats an odd type detect. We did have a few problems with that in some
kernels. Using setserial to force the type to 16550A may help
