MODGPS problems retrieving data

I'm using the MODGPS library with a Copernicus II GPS module. I ran the code as instructed. For the NMEA ports of the GPS, the baud rate is listed as 4800 so that is what I set it to initially. When I do that, I get nothing at all, no output. When I change the baud rate to something like 9600, I obtain output but it's just all zeros for latitude, longitude, etc. I know the GPS works fine because when I connect it directly to my laptop using the Trimble GPS studio program, I get correct data. But through MBED, I'm able to get nothing, especially when I set it to the corresponding GPS baud rate of 4800.

Any help or suggestions would be greatly appreciated!

How did you wire the Copernicus II GPS module to the mbed? Could you post a wiring diagram?

Thanks!
