I would like to interface with Pluto a self made project who permits control some devices. It run on a 232/485 interface. I saw an exanple to control A/V device Denon who permits to send/receive 'character' on a serial RS232, for example to implement the ON command is <$"PWON\r"$>. My question is, it's possible work in 'hexadecimal code' instead 'ascii code' ?
I'm waiting suggestions....
