There is no hardware available to support and interrupt output on DSR. It simply does not exist - no free outputs on the MCU and no driver for the software to activate. > Frankly, I am a bit surprised that it wasn't already > built in, Why would any transceiver incorporate a full three pair (TxD/RxD, RTS/CTS, DTR/DSR) interface if it had no need for it? Kenwood and the recent Yaesu rigs use RTS/CTS handshake but I can't think of any transceiver that even implements DTR/DSR. 73, ...
