WRITE PORT: Enter the port number (0Ć3) followed by a carriage
return.
REGISTER: Enter the register number (0 to 3) followed by a
carriage return.
At this point, if the entered rail location cannot be written to because
the register does not exist or the rail is an input rail, the appropriate
error message will be displayed and the operation will be terminated.
