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