I have a couple of SSR-6Tr boards but can't talk to them properly. Here
are the things I've tried:

The receiver does not respond to other @@ commands listed on the
firmware v1.73 technote.

I tapped the UART Tx pin on the u-blox module; I'm seeing NMEA on one
receiver, NMEA + u-blox binary on the other.

Did anyone manage to communicate with the SSR-6Tr in Motorola or u-blox
mode? I'm planning on using the USB port of the LEA-6T, but soldering
might void the warranty.
