Hi Steen,
I believe there is only one approach to this.
Use any terminal program. If you are using DOS then any old kermit,
telix, etc. will do.
You can use hyper terminal if using windows.

All your commands should be keyboard driven, so that a demo is as simple
as running any terminal program, so you can test and demonstrate your
hardware with simple keyboard commands.

Here are two PIC examples:

I did a thing a few years back when I first got started on PICs.
Have a look at:
http://www.dontronics.com/picex.html
An 18 bit input/output device driven from RS-232 using a 57, and all
done from the keyboard. This one is a little dated. I have also produced
some code for the 84 and may end up throwing the source and hex files
into my download dungeon, so others may get some use out of it. There is
basic programming examples on line which should help you with your
current problem.

Myke Predko has recently done an auto-baud RS-232 to LCD using a 61.
This is distributed by Wirz Electronics, and all the files, including
the commands can be found at:
http://wirz.com/sli/bench.html You will find most of it in the pdf file.
This again uses only characters that can be generated from the keyboard
for control.

It really makes it simple for design, testing, demonstration, training,
and sales if
you can run it all from a keyboard command set. OK, you wouldn't load a
full graphics character set into an LCD with the keyboard, but it should
be able to be done.
Use of special characters and escape sequences will allow additional
control.
