The following user program example shows how to return the Serial Gateway to the not prohibited sta-
tus after the ExecPMCR instruction is executed and the sequence is completed. (This example uses
port number 1 of a Serial Communications Unit with unit number 2. Note that in this example, the
sequence number specified by the ExecPMCR instruction is not specifically indicated.)
