Err, isn't that what I was suggesting. A simple double-pole changeover
switch with the fixed contacts cross-connected so as to swap TxD and RxD.
Finding a ready-wired switch is probably a lot harder than soldering in
those 2 links.

However, a terminal should only need TxD and RxD
(if it _requires_
hardware handshake, then it's not going to work with an awful lot of
things that work with a real VT220). In which case all you need to be
able to do is swap over those 2 pins, taking a simple DPDT switch.
Sometimes a simple solution exists :-)
Why not simply use a made-for-the-purpose T-switch? Is turning a
knob too difficult?
