+New - March 2018
+Using opto isolated serial port, paralleled up using same pair to multiple boards running this code.
+New feature - commands have optional prefix digit 0-9 indicating which unit message is addressed to.
+Commands without prefix digit - broadcast to all units, none to respond.
+Only units recognising its address from prefix digit may respond. This avoids bus contention.
+But for BROADCAST commands, '0' may respond on behalf of the group
