When you change to Command mode your user-defined LEDs remain in
their last state until you re-enter Run mode.
Input and Output Arguments
This routine has two input arguments and no output arguments.
The first input argument activates or de-activates LED1. The second input
argument activates or de-activates LED2:
1 = activate LED
0 = deactivate LED
Any other value has no effect on that particular LED.

transmission of a data packet is in progress. You should write your user
program so that it completes any transmission before performing CALL
113. This call clears the PRT2 transmit and receive buffers.
