Purpose
Use CALL 113 to disable DF1 driver communications. This routine has no input
arguments and no output arguments. This CALL terminates DF1 communication
immediately, even if the serial 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 transmission and receive
buffers.
