    RCDSL.H and RCDSL.C is an INOFFICIAL implementation of the
- 
 
 30 
    communication protocol used by DSL receivers of Act Europe.
- 
 
 31 
    The DSL receivers have a serial communication port to connect
- 
 
 32 
    two receivers in diversity mode. Each receiver is sending the
- 
 
 33 
    received servo signals periodically over this port. This fact
- 
 
 34 
    can be used to connect the receiver to the control unit of the
- 
 
 35 
    model via UART instead of evaluating the PPM signal.
-

    If you have any questions, fell free to send me an e-mail.
