I'm having problems using a Sunix PCI card with 8 serial port on a
Soekris board. This hardware will be used as a console server: each of
the 8 serial ports will be attached to the console of other Soekris box
to provide out of band management.
When I attach the console port of a managed box to any port from 2 to 8
of the 8x serial card, I get garbage.
If I attach the same hardware (cable and managed box) to the first port
of the 8x serial card, I get clear text.
The command I use for the firs port is :
# cu -l cua03 -s 19200
and everything works fine.
To use the 8th port, I use:
# cu -l cua0a -s 19200
and I get garbled text, almost like when the baudrate is not correctly set.
This drive me to thing that my problem comes from the way I create the
missing /dev/ files. Right after the install, the /dev/ folder contains
only files for 4 ports:
# cd /dev
# ls cua0* tty0*
cua00 cua01 cua02 cua03 tty00 tty01 tty02 tty03
#
I'm creating the missing dev files with the following commands:
# cd /dev/
# /dev/MAKEDEV tty04
# /dev/MAKEDEV tty05
# /dev/MAKEDEV tty06
# /dev/MAKEDEV tty07
# /dev/MAKEDEV tty08
# /dev/MAKEDEV tty09
# /dev/MAKEDEV tty0a
# ls -l cua0* tty0*

All hardware is new, and I've tried with two different cards of the same
model.
I'm runing OpenBSD 4.5 stable, but I get identical results with OpenBSD
4.4 stable (26/04/2009).
I've tried using directly mknod instead of using MAKEDEV.
Do I have anything to do to use this card excepted the creation of the
/dev/ttyOx and /dev/cua0x files ?
Does any modification has to be done to the kernel with a config -e /bsd
command ?
More details about the card:
