[ntp:questions] Setting the COM port for the NMEA driver

[David J Taylor]

Folks,

I've looked through the documents, and I can't see how to set the COM port 
for the NMEA driver on Windows.  Background: I have a GPS 18 and USB 
serial converter, and I wanted to see how well that actually performs.  It 
supplies data on COM4, so I need to tell NTP that's where to look for the 
serial data, but I can't see a fudge or mode parameter which allows this.

Does NTP even allow COM4?

Thanks,
David
