The box is running 4.8-STABLE and is otherwise up-to-date. apcupsd is telling me that it cannot communicate with the UPS via the serial port. Both the cable and UPS are fine, I can commuicate with the UPS with the same cable on another 80486 with a 16550A serial port. Also, the apcupsd.conf has been successfully tested on another machine. How can I test the serial port itself to see if it's working? I tried cu -s 2400 -e -o -h -l /dev/cuaa0 and said it was connected. I exited cu but now cannot attach ( cu: /dev/cuaa0: Line in use ). Obviously I don't understand the fundamentals and tools necessary to communicate with a serial port. The handbook and list archives haven't been much help. Could someone point me to a FAQ/archive/tutorial on how to debug a serial port? -- Regards, Doug _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
