You could just reference the NTP refclock driver.  It determines the model
and does appropriate initialization.  It's a bit more flexible than some
drivers since it uses a configuration file rather than just a mode
selector.  I suspect the sawtooth data is in the special status "file".

 * Driver for some of the various the Motorola Oncore GPS receivers.
 *   should work with Basic, PVT6, VP, UT, UT+, GT, GT+, SL, M12, M12+T
 *      The receivers with TRAIM (VP, UT, UT+, M12+T), will be more accurate
 *         than the others.
 *      The receivers without position hold (GT, GT+) will be less accurate.
