Tips and questions relating to the GPS modules from SFE

Does it have to get a lock before talking?

At the moment, mine is powered up, and has been for some time, but isn't saying anything.. I'm indoors, so maybe it can't get a lock.

Red light is on solid.

I did see it talking earlier, but had to power down, and it hasn't talked since.

I'm using an Atmel M128 to talk to it, TTL level of course, using USART1.

5S after powerup, I send it the WAAS on sentence.

I verified this with a serial terminal.

I get no reply to this.
