Hi All,
I am trying to install a 2 port serial card. I have been googling and
found some info but just need the steps made a bit clearer. I
understand that I need the lspci -vv (below) to get the values for
the card. I have also printed the dmesg output as well. I also read I
need to MAKEDEV but I tried this and created a dev directory with the
name of the new tty device I was trying to create. Any help, manuals
would be a great help.
Thanks,
Tony.

ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS4 at I/O 0xd000 (irq = 11) is a 16550A
ttyS5 at I/O 0xcc00 (irq = 11) is a 16550A
It seems to me the kernel found the two new serial ports named ttyS4 and
ttyS5?
HTH,

I think you are right. From the looks of things, Linux know how to
handle that PCI card, and is assigning the ports to /dev/ttyS4 and
/dev/ttyS5 (or /dev/tty/S4 and /dev/tty/S5) I believe the reason it is
not using /dev/ttyS1 and /dev/ttyS2 is that there are addresses
associated with /dev/ttyS0 through /dev/ttyS3 and they are not always
detected at boot time, depending on boot parametors. (COM1 through COM4
in DOS.) So the PCI ports are assigned to the ports after them.
Depending on what you are planning to use the ports for, you will
probably be creating, or having the system create links to them from
more descriptive names. (modem, mouse, pilot, camera, etc...)
