Gern! Great it did indeed help al little bit to get this working.

You could use any terminal program, or even run "cat /dev/ttyS0", but

Just deployed the 4.2.4p8 NTP client to 50 Windows 2003 SP2 servers, and
all seem to be running fine...except...

Thanks Martin for your reply!

Usually, that sort of hardware has a way to turn off the interrupt.
It's something like you write a bit in a register to "ACK" that
interrupt. When the external signal turns off, it clears that bit.
