Pil-io serial and remote keyboard

[J-F Garnier]

That's correct, the PIL-IO is not compatible with the use of a remote keyboard with the HP71 KEYBOARD IS command.

The problem with KEYBOARD IS is in the way the HP71 is detecting that keystrokes are available. It uses the HP-IL Service Request support, and the PIL-IO doesn't generate Service Request when data is available in the input buffer.
I didn't anticipate this use case with the PIL-IO !

However it should work fine with the HP-75 KEYBOARD IS that doesn't use service requests.

It could be possible to add the Service Request for data available. The latest PIL-IO firmware already supports HP-IL Service Requests, but not in this particular case.
