		mAr	Marathon Monitors protocol
bAud	Baud Rate	1200, 2400, 4800, 9600,
		19.20(19,200)
dELy	Delay - quiet period, required by	no	No delay
	some comms	YES	Delay active - 10mS
	adaptors
Prty	Comms Parity	nonE	No parity
		EvEn	Even parity
		Odd	Odd parity
The following parameters only appear if the function chosen is Modbus protocol.
