the RTS pin is unasserted.
In normal usage, the RTS and Clear to Send (CTS) pins work together,
and are used as standard handshaking pins for data transfer. In this
case, RTS and CTS are automatically managed by the DTE and DCE. However,
there is nothing in the RS-232, or the RS-484 standard that states
the RTS pin must to be used in any specific way. Therefore, if you
manually configure the
RequestToSend value, it
is probably for nonstandard operations.
If your instrument does not use hardware handshaking in the
standard way, and you need to manually configure
then you should configure the
none. Otherwise, the
that you specify might not be honored. Refer to your instrument documentation
to determine its specific pin behavior.
You can return the value of the CTS pin with the
