    I've recently tried to use two different brands of 8-port PCI serial
    cards in an FC2 machine. It didn't work and I was forced to downgrade
    the machine to FC1. This is a heads-up if you want to try anything
    similar.

    The machine has two on-board serial ports, ttyS0 and ttyS1, and a PCI
    modem card, ttyS4. When the 8-port card is added to the system, it fails
    to notice the modem and starts numbering ports with ttyS4. But it only
    goes to ttyS7 and then wraps around. It does notice that 0 and 1 are
    already in use so it allocates ttyS2 and ttyS3. Then it stops, giving
    me only six new ports and losing the modem.

    With cooperation from one of the vendors, we tried to work around the
    problem using setserial. All attempts to assign any of the new ports to
    ttyS8 and above failed. While the FC2 distribution creates device nodes
    for ttyS8 and many others with higher numbers, it appears impossible to
    actually use those nodes.

    If this is a known issue, is it expected to be fixed with FC3?
