Serial Com Port Problem ttySx
in I/O Devices
Hi all
CentOS 5 on a DSEB-DG motherboard
I am having trouble communicating with my APC UPS on /dev/ttyS0.
What I do know:
UPS and cables are ok they work ok on my other server. CentOS on a Intel S3210SH M/B
Comparing the serial ports in the Hardware browser I notice that the Working system (Intel) is listed as such
16500A-compatible Com port
16500A-compatible Com port
16500A-compatible Com port
16500A-compatible Com port
16500A-compatible Com port
16500A-compatible Com port
16500A-compatible Com port
The non working system lists
16500A-compatible Com port
16500A-compatible Com port
16500A-compatible Com port
The com ports are set in the bios as:
Com1 3F8/IRQ4
Com2 2F8/IRQ3
So I can see why the system does not work.
What I do NOT know:
How can I correct this problem. Do I need to re-install the drivers? if so HOW.
Thanks for taking the time to read this.
Dave

grep serial /var/log/dmesg
and
cat /proc/tty/driver/serial
you may need to run both as root.
