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. :-(
I have a few of those. Really, really neat little boxes. I've been
similarly unable to find out anything about them. :-(
I use one on a daily basis at work.
What do you want to know?
