In broadcasting - we learned very quickly interfacing equipment with RS232,
that if it worked once it would continue to work.
Back in the beginning of using RS232 interfaces (cira. 70s) one of our the
engineers made a box with input/output pigtails in both male and female with
a rotary switch that switched between straight through and "reverse" for all
the various signals. Later we added 9 pin pigtails. Using that box quickly
let us know what would work and how to make the interface cable.

I never really understood RS-232 until I read “Technical Aspects of Data
Communication” by John McNamara. Very clear. Not sure it is worth getting
the book just for that, but you might check a library.
