Post Access all pins on built-in serial port?
Hi there, I'd like to connect a GPS receiver to my fitlet2's serial port to send a pulse per second reference for NTP. PPS is usually sent on the DCD (Data Carrier Detect) pin for NTP/GPSD, but I think the default pinout for the serial port doesn't expose that pin to the connector. Is there any way to access all pins, or at least DCD, for that built-in port?

I'll be using the dual NIC FACET so I won't be able to use the serial port FACET, even though that might give better pin support.

Thanks!

The fitlet2's RS232 support has only 4 pins:

1. TX
2. RTS
3. RX
4. CTS

Unfortunately, there's no DCD support.
