The Serial Box <https://bit.ly/S-BOX> (S-BOX) was specifically designed to
make it easy to connect multiple devices in parallel to any transceiver's
serial port, including a PC, KPA500, KAT500, KPA1500, SteppIR Controller,
Kessler AT-Auto, Shackmaster SM-8, etc.   One device is connected to Pin 3
(usually the PC running logging software to do the polling), and the rest
are wired in parallel to listen to the radio's responses on Pin 2.
AutoInfo mode may also enabled to let all devices track the transceiver's
frequency automatically when no PC or logging software is being used.
