The RS232 serial port interface for kForth (-32/64 for Linux) has been

CTS etc.

 RS-232 is good. I used to have a board called the octopus. It had two
rs-232 connector on both ends to handle all sex.  Had pinouts in between
to swap tx/rx and/or tie HTS and CTS to ground or high (I forget).

Yes, I know RS-232 well from past experience using it to control instruments and test wireless communications systems (long ago). For interfacing the serial port to read an external switch, the other modem lines can be used to read up to 3 switches (maybe 4).
For my audio recording program, I currently have one button to start and stop recording. I plan to add two more buttons: one to start and stop playback of the last recorded file in the sequence,and another to redo the last recording. All three should be readable from a single serial port.
