I want to send a non-RS232 type signal using the 3DR telemetry radio. No start, stop bits etc. Just bits to be reflected exactly on the other end.

They do have a format but its not the standard RS232 async format we all know and love.

I'm trying to inject the signal via the standard DF-13 cable.

Is there any way to do this?

The modem works, in every other way as I need for this project.
