Hi,

typing setserial -g /dev/ttyS? gives:

/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

Which seems okay?

However, cat /dev/ttyS0 gives absolutely nothing, no chatter, nothing.

I installed minicom, which also required a modem communication file
thingie (?) loaded it up and configured the modem to /dev/ttyS0, but am
unsure how to probe further to see if a) the serial port is configured
correctly, or b) whether the UPS is trying to "say" anything.

This UPS worked a treat on my SuSE 9.3 machine, but since upgrading to
SuSE 10 (fresh install, new hardware) hasn't given a peep.

Anyone got any experience with COM ports??

Cheers, Jon.
