Sadly, getting another machine is not an option. I have this machine under contract, so I really need to find a way. The main problem is that this machine came with a serial "management" port instead of a regular serial port. When making the above I/O system calls while connected to that, I don't get invalid responses, but I also don't get time values other than 0.0000000. I've hooked up the same GPS device to a Sun Fire v480's serial port and it worked fine. (I can't use that machine however). I wonder if there is a way to configure the management port to act differently, say, like a basic serial port? _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
