/dev/ttyS?

Had a customer that purchased an APC Back-UPS Pro 650 for the linux
server in his office (he jumped the gun on me - thinking he got a deal /
I was thinking Smart UPS 1000).

Anyway, downloaded the new PowerChute RPM from APC and installed it but
it can't seem to find the serial port.

I don't have a monitor/mouse/keyboard on this beast but I may actually
have to do that to figure out where the serial ports are in the scheme
of things in bios but can anyone tell me - how can I see which serial
ports are active in a log or a command? (RH 7.1)

lspci & pnpdump - /var/log/dmesg and /var/log/messages don't seem to
mention any of these ports. They seem to find the US Robotics Sportster
33.6 internal modem and that's it.
