Yes, I got PPS.

You mean 2947?

Yes, I see that.  But still nothing in gpsmon.

Been working for a day for me on SiRF III.  SiRF IV still broken.

I guess I'll have to read the doc.

Here is Rev 9 (2010):

http://gps.0xdc.ru/static/sirf/doc/SirfStar/GSD4e%20OSP%20Manual%20%28CS-129291-DC-9%29.pdf

Looks like ID 0x86 is still the one, the SiRF IV has two serial ports,
can't beleive they hooked up to the secondary one.

Here is what raw gpsctl writes:

gpsctl:PROG: SiRF: sirf_speed(19200,N,1)
gpsctl:PROG: SiRF: Writing control type 86:
gpsctl:IO: => GPS: a0a200098600004b000801000000dab0b3

That matches the doc, except I did not check the checksum.

BTW, gpsd ^C handing is broken:
