property RTS : Boolean
Default: True
Determines the current state of the "request to send" (RTS) signal.
This signal is usually used for hardware flow control, in which case your application does not need to set it directly. Less frequently, devices require that your application raise and lower RTS to control the device, or require that RTS be permanently set. Use this property in those cases.
The following example lowers the RTS signal after opening the port and later raises it again:
ApxComPort := TApxComPort.Create(Self);
ApxComPort.Open := True;
ApxComPort.RTS := False;
...
ApxComPort.RTS := True;
