When I have used RTCM, with Skytraq, the GPS has two serial ports.
One that GPS uses, and the other that is used to RTCM. In that case,
gpsd is not in the loop. Does you GPS have two inputs?
I think gpsd knows how to decode various RTCM packets, but not how to pass
them on to the GPS. I could be easily wrong on that.
