SIRF2

GPIO3 - power control pin for SirfLoc firmware
GPIO4 - power control pin for standard GSW2 firmware

Citing GWG6203-X DATA SHEET - Rev 2.00 07/2005

When you want to use SiRFLoc Client firmware, you have to connect GPIO3 (Pin 8) with
GPIO3/4 (Pin33) and GPIO3/4 (Pin33) is power control pin for input. On the other hand,
when you want to use standard GSW2 firmware or SiRFXtrac. Firmware, you have to
connect RFPC1 (Pin 9) with GPIO3/4 (Pin33) and GPIO3/4 (Pin33) is power control pin for
input.

SIRF3

Most receiver manufacturers have zeroed the carrier phase data in the MID28 message (early TomTom firmware is the only known exception)

RTCM2 support

SiRF accepts RTCM type 1, 2, 3 and 9 messages through one of the serial ports. The default differential behavior is to accept RTCM messages through Port 2.
