138 a headset for training purposes, or even your ham radio transceiver.
140 the latter, simply connect an NPN transistor to the serial port
142 emitter connected to ground, base connected through a resistor
143 (few kiloohms) to RTS, collector to the key line of your transceiver
144 (assuming the transceiver has a positive key supply voltage and is keyed
145 by grounding the key input line).
