Hi Nobby,
wonderful... That clears my doubts.
Just for knowledge, how can I configure PIND7 as RTS, do you have the code for it?
Thanks in advance.
Sorry I've never needed CTS or RTS in any application. I'm fairly sure its only modern use is for UART communications which have multiple devices on the shared three-wire interface and have an address they respond to. There are still some ancient RS232 devices out there which require CTS & RTS for end-to-end comms.
From what I have seen with the .Net framework though, you need to specify hardware flow control on the SerialPort object. It supports XOn/XOff and RequestToSend or a hybrid. You do this through the SerialPort.Handshake property at runtime. I believe once you configure your serial port this way, it will configure the RTS and CTS pins to function with the serial port.
