Hi there all.

First of all, to give you a little run-down on my situation... I work on an oil rig and I have been playing around building and testing my APMega after hours. I haven't been able to test GPS yet as there are restrictions on the use of electrical equipment outdoors..... might be sneaky later :0)

I have assembled my mega and have been playing around with the onboad USB port (Port0) configuring this as the GCS port and watching the data "arrive" in the serial data (raw) window in HappyKillmore's ground control station. All is good and all the information appears to be translated correctly.

Next I thought that I would change the config.h file and define the GCS port as port3 (telemetry port) and watch the data stream into Happy killmore's via the telemetry port. After defining port 3 for GCS use and setting the baud rate I used a USB to serial port adapter to create a new com port for the APM to send data to, matched up all baud rates (device manager and in happy killmore) and double checked everything but all i'm getting in the serial data window is

OUT:MAVLINK (followed by the usual sort of 2 digit character sets)

IN: unknown command (followed by weird characters in no specific order i.e gobbledegook)

Is telem port3 a simple serial port or is there something i'm missing?

Is there a particular setting that need to be applied to the serial port on the PC?

I'm just trying to get my head around a few things before I go home and get stuck in properly

Sorry if this is a stupid question, i'm running pretty low on sleep ;0)
