I think I found the programming specs:

Glen - the HP button box you describe is amazingly similar, but the case
is a bit different. Those buttons don't look like they have lights ...
the IBM version does, and the lights are controllable from the host
machine.
Mike, the HP A4363A button box does have LED indicators in each button
and does have the same button layout as IBM button box shown in the
webpage you referenced.
It also does have an LEDs on command, which is 0x75 followed by 4
button mask bytes.
The other commands for the HP A4363A button box are:
Reset - 0x20
Setype - 0x71 followed by 4 button mask bytes. A clear mask bit means
report press only, a set mask bit means report press & release.
Autosend - 0x73 followed by 4 button mask bytes. A clear mask bit
means that button is ignored.
According to the webpage you referenced the IBM button box mask bytes
are two hex characters per byte, while from the HP documentation it
appears the mask bytes are raw binary byte values.
