130 the latter, simply connect an NPN transistor to the serial port
132 emitter connected to ground, base connected through a resistor
133 (few kiloohms) to RTS, collector to the key line of your transceiver
134 (assuming the transceiver has a positive key supply voltage and is keyed
135 by grounding the key input line). A capacitor (some nanofarads) between
136 base and ground is advisable to keep stray RF away,
