Umm.. note the prompt ;)) I'd done an su root before testing to avoid
permissions problems. This seems like a problem with nqc on LinuxPPC 3Q99,
but I can't understand quite what it is as the tower obviously works -
the green light is visible and it maintains a steady brightness and it works
fine from Windoze. The only thing I can think of is that the baud rate or
serial format isn't correct - the serial port works fine with my modem so
it's not a hardware problem.

| (...) Have you tried using setserial to set the correct baud rate and other options? Also note that when using "su" it sometimes doesn't take over all the settings from the user account that you used to log on. Perhaps the sudo command would work (...)
