124 it is possible to key an external device, like a sidetone generator with
125 a headset for training purposes, or even your ham radio transceiver. For
126 the latter, simply connect an NPN transistor to the serial port
128 emitter connected to ground, base connected through a resistor
129 (few kiloohms) to RTS, collector to the key line of your transceiver
130 (assuming the transceiver has a positive key supply voltage and is keyed
131 by grounding the key input line). A capacitor (some nanofarads) between
132 base and ground is advisable to keep stray RF away,
