Parameters

Comments

SYSTem:COMMunicate:SERial[n]:CONTrol:RTS < Rts_cntrl> controls the behavior of the Request To Send output line. RTS can be set to a static state (ON OFF), can operate as a modem control line (STANDard), or can be used as a hardware handshake line (IBFull).

Parameter	Parameter	Range of	Default
Name	Type	Values	Units
rts_cntrl	discrete	ON OFF STANdard IBFull	none

•The following table defines each value of rts_cntrl:

Value	Definition
ON	RTS line is asserted
OFF	RTS Line is unasserted
STANdard	RTS will be asserted when the serial interface is
	ready to send output data. Data will be sent if the
	connected device asserts CTS and DSR.
IBFull	While the input buffer is not yet at the :STOP
	threshold, RTS is asserted. When the input buffer
	reaches the :STOP threshold, RTS will be
	unasserted.

•DIAG:BOOT:COLD will set … RTS to ON.
