Re: [questions] Re: GPS+PPS vs NTP server, why a huge offset ?

I use the Raspberry pi with GPS hat and it works great.  100 dollars and you have a great NTP server

CTS is on pin 5, and RTS on pin 4, on an RS232 connector, which should
be a DB-25 one.

The DE-9 connector, used on PCs, is a TIA-574 connector, not an RS232
one, and RTS is on pin 7 (although not useful in this context, as it is
output from the PC).
