Setting com port questions

I have a piece of equipment, a Baytech RPC-3, that I need to communicate with through the com port.
I normally use this equipment at home and am able to connect to it without problems using FC5 and minicom; I brought the equipment into work and cannot get my pc, using Suse 10 and minicom to communicate with it.
Settings for minicom are the same on each machine. The main difference between the machines is that on the FC5 machine I have two com ports and the Suse machine only has one com port. I have tried both ttyS0 and ttyS1 as the serial device setting on minicom without any success.

The RPC-3 has indicator lights for troubleshooting, and indicates that there is a "Cable or hub connection fault".

Running setserial in the Suse box gives the following information:
sport:/home/thumper # setserial -av /dev/ttyS0
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test

Required settings for the RPC-3 are 9600, 8N1.

I am not sure if I need to run setserial to try and set the Baud_base to 9600, and I sure dont know how to indicate the 8N1 in any config file.

Can someone point me to what I need to be looking for on this because I am pretty lost.
Thanks

LIEBERT(8)							    NUT Manual								LIEBERT(8)

NAME
liebert - Driver for Liebert contact-closure UPS equipment NOTE
This man page only documents the hardware-specific features of the liebert driver. For information about the core driver, see nutupsdrv(8). SUPPORTED HARDWARE
This driver supports some Liebert UPS equipment with a contact-closure interface. This includes the UPStation GXT2 with their contact-closure cable. The smart mode ("Multilink") cable is not supported by this driver. EXTRA ARGUMENTS
This driver does not support any extra settings in the ups.conf(5). BUGS
This driver does not yet support shutdowns by raising DTR. Be aware that shutdowns are not possible with the stock contact-closure cable. You may have to build another cable with DTR connected through to the UPS for it to work. There is no way for this driver to detect the hardware or cable. It will start up successfully even if no UPS is present. This is a fundamental limitation of any contact-closure driver. SEE ALSO
