COM Port DTR, and RTS support
by manton » Mon Jan 09, 2012 9:54 pm
Would it be possible to create a COM port object that has support for controlling the DTR, and RTS control lines? This would be useful for communicating via RS-485, which is usually half-duplex, so one of the control lines is usually used to enable the output drivers of the RS-485 transceiver.
Sometimes these lines are also used to put a target device into program mode, and this would allow a Flowstone app to update firmware on the remote device, which could open up a number of useful applications (at least for me).
