This code is used to control a transmitter. Serial data is loaded, based on it a relay is triggered. This works OK, when no more input is provided, I want the relay to stay on.

THIS CODE WORKS IN ALL WAYS EXCEPT WHEN IT LOOPS BACK TO GET MORE DATA, AND NONE IS BEING SENT, IT TURNS OFF THE RELAY THAT HAS BEEN SET ON. i NEED TO KEEP THE RELAY SET WHEN NO SERIAL INPUT DATA IS THERE. WHEN DIFFERENT DATA, OR THE SAME DATA IS INPUT, IT AGAIN WORKS AS EXPECTED UNTIL LOOPING BACK TO LOOK FOR MORE DATA. THE RESULT, IS THAT THE RELAY IS JUST PULSED ON UNTIL THE NEXT LOOP THROUGH. CAN ANYONE HELP ME TO GET THE RELAYS TO STAY ON WHEN SELECTED UNTIL NEW DATA IS INPUT FOR A DIFFERENT ONE? (ALSO, I HAVE NO IDEA WHY THIS WANTS TO DISPLAY COLOR HERE INSTEAD OF JUST PRINTING THE
TRANSMITTER CONTROLLER. NEEDS TO LATCH RELAY AS SET WHEN NO SERIAL DATA IS ENTERED.
