Owner`s manual

The first number parameter is a "command-id" number, defining the specific action for this type of command, and which parameters
follow to complete the command. If a Command (optionally) includes an extra parameter, the last parameter is presumed to be a
checksum. An example command:
*CW,40,3,5,4 <cr>
Similarly, VauxProtocol Messages begin with an exclamation (!) character, followed by one letter defining the type of message, one or
more comma-delimited decimal number parameters, and a terminating CR/LF. Optionally, you can force leading zeroes in Messages,
for fixed three-digit parameters (eg: 003,012). Many Commands return the same status Message – simplifying parsing code. An
example message:
!S,40,3,5,4 <cr>
The serial port requires 38400-baud, 8 data bits, no parity, 1 stop bit, with Xon/Xoff flow control
enabled. 38400 is recommended, but 1200 to 115200 is available via a configuration command.
