Hi All, Is there a serial PPP Driver for linux, that is capable of operating in half duplex mode. I have a radio that operates in half duplex mode and it has a serial interface. I want to establish a Point to Point connection between two Radios. Do you have a serial port PPP Driver that supports half-duplex mode of operation ?. i.e. I need RTS to be active when you are transmitting data and to be inactive to receive.
