Description

Some serial-to radio cables use RS232-to-TTL converters, and/or have TTL logic to split out TX and RX from just one signal line (eg, most of the Icom radios). Some of these converters generate the necessary power from RTS/DTS and ground. The better ones tend to generate the power from the differential between RTS=low and DTS=high (or vice versa), allowing full RS-232 signalling levels.

The latter case requires that DTS and RTS be set differently. Note that "Ham Radio Deluxe" has had this option (stored on a per-radio configuration basis) for years, as has RumTrol (for the Icom IC-7000).
