Have just installed a 4port serial card, I can say that it's
The card that I used had 4 separate serial chips on it (16550)..
(Do you know what your's are? 16550A, 16650? )
You need to know the IO address for each port (different for each one)
and the Interrupts (IRQ) used by each port (which may be shared).
[ Does the card have jumpers on it to set the Interupt
and IO address for each port? Or is it configured some other way? ]
( you'll have the serial module (serial.o) because it's a RH 6.1
and it will be working.. you'll know this if you have a serial mouse
use something like the following... for each port...
setserial /dev/ttyS4 port 0x2a0 irq 4 uart 16550
setserial /dev/ttyS5 post 0x2a8 irq 4 uart 16550
... etc ...
[ these were my settings, check 'ma
It you add these lines to the file
then they will get run every time your machine is booted.
You will need to do the following as well:
mknod /dev/ttyS4 c 4 68
mknod /dev/ttyS5 c 4 69
mknod /dev/ttyS6 c 4 70
mknod /dev/ttyS7 c 4 71
mknod /dev/ttyS8 c 4 72
mknod /dev/ttyS9 c 4 73
This creates the character device nodes, and only needs to be done
You should be able to talk to each serial port by reading/writing to
the above character devices?
