We are trying to get a keyboard running so that folks can program their 9100's, the built-in keyboard is a pain, plus is limited in it's capabilities...<br><br>
What if an old VT-100 terminal or the like was used? Or a simple interface program...if anyone had a keyboard and a Logic Analyzer they could record the data stream for individual key presses, plus see what happens when the machine is first turned on for any chatter between the keyboard and the base.<br><br>
Anyone know if you can plug the keyboard in after the unit is already on and if it will then find the keyboard with a RESET?<br><br>

It's starting to sound like the 9100 keyboard just sends simple text as<br>
it's typed. If that is what it is REALLY doing this should be very<br>
simple. (Uh, what are we trying to do again?)<br><br>
