IBM 6094-020 Lighted Program Function Keys

[Michael B. Brutman]

I'm getting a little closer ..

I have the power adapter now and the correct cabling.  This device 
communicates over the serial port, but I have no idea how to talk to it, 
and I haven't even been able to get it to transmit noise on the serial 
port to the host PC.  (I've tried a variety of bps rates.)

Does anybody have IBM book SA23-2646-01 "Hardware Technical Reference: 
Options and Devices" ?  The protocol for speaking to this thing might be 
in there ...

If anybody else has one connected to a PC RT or an old AIX box, it would 
be possible to reverse engineer the protocol by tapping the serial cable 
and watching what comes across.

It's a neat looking piece of hardware - 32 buttons, each having a 
controllable indicator light.  But I'm getting grumpy because I have no 
idea how to feed it. :-(


Thanks in advance,
Mike
