I'm working in a Beaglebone environment - ARM, Debian- so the Windows 
tools don't work.  Before I go out and write python code to push 
characters out the serial port and get the output, I was hoping that 
someone had done some of this before.. I can do the conversion from a 
binary file to RINEX somewhere else.

rtklib might do the trick, but might also be overkill.  It seems that 
all I need to do is send the right strings to the GPS and it will start 
spitting out the right binary messages, which I then capture and post 
process. (perhaps using rtklib's utility to do binary to RINEX).
