I've just got a Rapco 1804M and while it works, within the limits of my
antenna placement, the RS-232 serial out doesn't read very well, and seems
to have incorrect characters. The voltage levels look OK, and the
terminal emulation program is set to 4800 baud, 8-bit, no parity, one stop
bit, no flow control. I've tried other combinations. As near as I can
measure, the baud rate is 4800.
Here's some sample output:

The same serial port works correctly with 9600 baud Garmin signal, and I
don't have any other available computers with spare RS-232 ports I can
test against.
Am I missing the obvious, or is there something wrong with the serial
port? I do appreciate that the serial port isn't critical to the correct
operation of the 1804M, but this has cast doubts about this particular
unit into my mind!
Thanks,
