Using terminal commands

RETURNS	The return result depends on the control byte. However, whatever
	the return result is, it includes the control byte.
REMARKS	The general behavior is that a PORT command issued on a certain
	port bit will override any previous PORT commands. For example,
	if a port was configured as input and then an MFR (monostable
	function) was issued, the port automatically switches to output. A
	new MFR or similar function clears the status of the port and starts
	from scratch, even if the previous command was not finished.
REMOTE	Yes, for the A720 and A723. If you are using a terminal window for
	the A720, you cannot issue the PORT command. If you are using a
	terminal window for the A720B, you can issue a PORT command
	remotely for an A720 or A723 RTU, but you cannot issue the com-
	mand for the A720B receiver. In other words, the base station can
	issue a remote command for an RTU, but it cannot issue such a
	command for itself. An RTU cannot issue the command at all, but
	can execute it. An axcpetion is the A723 RTU that accepts this
	commands also over the serial line.
EXAMPLE	For RDP:
	6789	PORT 0
	6789	PORT 0 1 0
	#
	For RDDR:
	6789	PORT 16
	6789	PORT 16 0 0
	#
	For ENOPC:
	6789	PORT 112
	6789	PORT 112 0
	#
	For RPNNER:
	6789	PORT 128
	6789	PORT 128 0 1 0
