:CONTrol:RTS
SYSTem:COMMunicate:SERial[n]:CONTrol:RTS <rts_cntrl> controls the
behavior of the Request To Send (RTS) 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).

Definition
RTS line is asserted
RTS line is unasserted
RTS will be asserted when the serial interface is able to send output data. Data
will be sent if the connected device asserts CTS (clear to send).
While the input buffer is not yet at the :STOP threshold, RTS is asserted.
When the input buffer reaches the :STOP threshold, RTS is unasserted.
• We recommend you set ...DTR and ...RTS to STANdard when operating a
modem.
• DIAG:BOOT:COLD will set ...RTS to ON
