Shouldn't be a big deal.  The way I set things up, RTCM2 and RTCM3 are
just additional packet types that the packet sniffer can recognize
(though it took some contortions to make this work for RTCM2 because it's
bit-stream with 30-bit words, not byte-oriented - you have to run a
separate state machine to sync to the packet boundaries).

So, basically, you can plug in both ports and GPS should figure out which is
NMEA and which is RTCM2 on its own.  At worst, you might have to tell the
RTCM2 port the baud rate with stty, but pribably you won't need to do that.
