Thanks. Can I please ask a couple other questions about this?

The documentation for it says that the serial interface is TTL levels
(which are 0-5v, if I understand correctly), rather than what would be
expected by a PC serial port (which are 0-15v, again IIUC).

Can this just be connected to the PC serial port, or will I have
to build/buy a TTL -> RS-232 converter/adapter?

I looked through the 'Comprehensive list of clock drivers' supplied with
the NTP software, and didn't see this device mentioned. Is it know by
another name to the NTP software?

Thanks again!
