I'm using the EM-406 and the SFE Breakout board, and I get NMEA data on COM1 at 4800bps, but when I try to switch to the SiRF protocol, it ignores me and continues spitting out NMEA messages.

I'm also having problems getting AVRStudio to connect with my STK500 programmer using the serial port.Ahhhh... confirmation! I switched over to another computer (which I've not been using because of other issues) and it has no problems switching the GPS over into the SiRF protocol. It can also communicate with my STK500 programmer as well. #@$& computers!!!
It's odd that I can receive data on the port (i.e. NMEA data from the GPS) but things that involves sending data via the port seem to fail. It's not a bad cable (I've tried several). This computer's been in operation for a year or two... might be time to clean the computer off and reinstall Windows.

FYI, you cannot pump raw RS232 signals from your computer straight into the GPS module.
