	/  RTS.
$SYNTAX$
	COM_RTS(<nComPort>,[<lNewRTSStatus>]) --> lOldRTSStatus
$ARGUMENTS$
	<nComPort> - Designates the port (1 to N) for which the number of characters in the input buffer is determined.
	<lNewRTSStatus> - Designates the status of RTS. .T. designates
	that the RTS signal is active, and .F. designates that the signal is
	inactive. If the parameter is not specified, does not affect the RTS
	exit signal.
$LANG_RU$
	<nComPort> -   .
	<lNewRTSStatus> -   RTS: .T.  
	, .F.   .    ,  RTS 
	.
$RETURNS$
	The returned value corresponds to the RTS signal status prior to
	the new setting, or in the absence of <lNewRTSStatus>, the returned
	value corresponds to the current RTS. A return of .T. indicates that the
	RTS is active (MCR bit 1 = 1). A return of .F. indicates that the RTS is
	inactive (MCR bit 1 = 0).
$LANG_RU$
	 .T.  RTS , .F.  .  
	 <lNewRTSStatus>,     
	.
$DESCRIPTION$
	COM_RTS() queries the RTS signal status.
	If the second parameter is not supplied, the signal status does not change.


	The COM_CLOSE() function resets RTS (to inactive). By contrast,
	COM_OPEN does not automatically make RTS active!
