Hi, I'm currently doing a project where I want to access my iPAQs DSR, CTS and DCD lines so that I can use them to power a small sensor platform that I've created. My plan is to use the Tx/Rx lines for communication with the board and the other handshake lines for supplyin the power needed.
When looking through the serial library I'm not really sure if I can find commands
for those three lines. But if there is another library that does this, how do I set them to constantly on and with one of them giving a negative voltage?
