Serial problems - UPS related.
Little problem here.
I had my APC UPS plugged into /dev/ttyS0. Everything worked fine. Then, I had to hook up an external modem. Due to some complications, it ended up being plugged into ttyS0 and ttyS1 during the course of the day. The modem has since been physically removed, and the device un-installed, first in 'neat' then by Kudzu during a boot up. Now, I plug the UPS back into either of the serial ports and I get nothing. No communication. Any idea of what the problem may be? Could the modem (or its ghost) somehow be hogging both ports? Or did it reset the speed of the serial port? If so, how the Hell do I set it back, and what the Hell should I set it back to?
All of this is happening on a RedHat 9 box with ssd 2.0 Beta 2 (which I have on another machine, identical to the one in question, and it's working flawlessly).
P.S.
I'm doing something wrong with setserial. No changes I make seem to take effect.
