Here is an except from a manual for a piece of hardware I wish to develop software for. However have no idea what the P3 rs232 protocol is. Hopefully someone here can help me out.
Protocol RS232: This is used to select the protocol on the RS232 interface. There are 3 options:
Enhanced - This protocol is here only for compatibility reasons. Not all features are available via this protocol.
P3 - If you are a software developer this is the preferred protocol to use. This protocol is also used for software like ‘Racewave’.
Remote - Allows the host computer to select the protocol by using a command. Use this setting when 12 used with Orbits.
