MAWD Altimeter Data Capture

A tool to configure a PerfectFlite MAWD altimeter and download flight data

The protocol is pretty straightforward:

Simply send the ASCII command over serial link to the MAWD, and receive the response

Serial data format: 8N1, XOn/XOff, 38,400 bps for commands+data, 9,600 bps for telemetry
