Telemetry support in app_rpt

Hi, I have been doing a deeper dive into the telemetry support in ASL v2.0.0. It appears that it uses a serial connection to a USB device called a ‘chameleon’, with what appears to be a relatively simple ASCII based protocol to acquire the data. Does anyone have any more information or a manual on the protocol, or documentation on what app_rpt sends or expects back? Thanks.
