This detail changes the whole thing.  It's time to bite the bullet and have
some dedicated hardware that will do exactly what you need.  I wouldn't
consider using a DOS-based system any longer.  It would be much less
expensive (even considering the re-programming) to use your own hardware.

There are simple ways to do what you need.  Google "basic stamp" and that
will get you started.  Many off-the-shelf "stamps" have a single serial port
built in.  You just need to figure out a way to add an additional port.  It
shouldn't be hard.

Messing around with Basic Stamps will give you ideas about hundreds of other
simple little projects that need just a little intelligence between two
devices.  There are many companies that started out selling products built
on stamps...
