OpenCPN - GPS Feed from PolarCOM


Apologies in advance if this has been answered already. I'm using gpsd to serve a single USB GPS stream to OpenCPN and various other gpsd-compatible apps. Works great, but I would like to add PolarCOM into the mix, and PolarCOM is not gpsd-compatible.

Is it possible for OpenCPN to take GPS signal from PolarCOM instead of gpsd. I see that PolarCOM can serve the GPS stream in many ways, but I don't see a way that OpenCPN can directly receive it.

I'm sure I can script up something with socat or netcat to mux the gps to several virtual ttys, but I was wondering if there's an easier way. Alternately, has anyone tried to write a gpsd client/daemon that can redirect the stream in a form PolarCOM can understand? Or maybe an OpenCPN plugin that does something similar?

I use Muplex. I got it from here: Muplex - OSD_Depth
I heard about it here: Soft Multiplexer for Linux

It set up easily and works.
