Honeywell TDC3000 Keyboard to PC interface

we are trying to emulate a TDC3000 Honeywell keyboard on a PC.  This
emulation can be done by a third party keyboard with Honeywell
customization (not preferable), or a real TDC3000 keyboard with built-
in interface for PC.

Are you aware of any interface where I could plug in TDC3000 keyboard
into PC and be able to catch keys, turn on LED lights, sound an alarm
etc.

Or is there an original Honeywell keyboard that is already pluggable
to PC but needs some software, driver that will enable this. I assume
the actual communication protocol is owned by Honeywell and not
publicly available.

Any ideas.

Thanks,

Rudy
