Since this is an experimental project, you can put an embedded controller
to work.  My choice is Intel 8751.  It has a conventional 8/9 bit UART
which you can use for communication with the main CPU, and 4 kbytes of
eprom which you use for the external uart control.  In other words,
program your own uart in software and use an 8751 i/o port for
the hardware link, and use the built-in uart to shuffle data to your IBM
PC or whatever, using its RS232 port.

It is doable, and not that hard.  Good luck.
