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
#
Thanks for the dmesg.
What's the output from: grep tty00 /etc/ttys on the soekris boxes that
you are connecting to the card?
For my PCEngines alix board I needed to change the baud rate from the
standard 9600:
alix:fred ~> grep tty00 /etc/ttys
tty00 "/usr/libexec/getty std.38400" vt220 on secure
alix:fred ~>
Hello Fred, thanks for your reply.
Right now, I could not answer to your question because I do not have
physical access to the hardware, and the Soekris box connected to port 8
has no system on it so the serial link is talking to the BIOS.
But anyway, the console server should be able to communicate with the
Soekris BIOS, and I get clear text on port 1 of the serial card when I
talk to the Soekris BIOS of another BOX.
I will have access to the hardware later today, so I will be able to
make any test anyone may suggest.
I'm pretty sure it is not a problem about setting up the baud rate on
either side of the serial link, because if I connect the exact same
equipment on port 1 of the PCI card on the console server (cua03), I get
clear text with the 19200 baud setting, and garbled text on any port
from 2 (cua04) to 8 (cua0a) with the same baud rate.
I'm not sure if it has any importance but I include below the /etc/tty
file of the console server (this is the unmodified file after the
OpenBSD 4.5 setup):
