[time-nuts] Serial port splitter s/w

[David C. Partridge]

I'm running Meinberg NTP on the Windows 7 x64 machine to which my Thunderbolt is attached.

I'd like to be able to share the serial port between LH and NTP so that I can run the machine as an NTP Stratum 1 server locked to the TB, and also be able to use LH to check things.

I looked around the with Google, and saw *numerous" serial port splitters.  Which is recommended?

Also what's the best way how to configure NTP to lock the the TB on a serial port?  Do I need to modify the TB to deliver the PPS down one of the serial data lines or will NTP work well by parsing the NMEA time messages?

Many thanks
