We have started 1100 driver 5-years ago (our drivers are cross-platform) but unfinished because of instrument absence under the hands.
No way to test and nobody needs it.
We also started a HP1100 emulator written in PHP

- but most of the protocol knowledge - is reverse-engineering. Need the documentation or actual instrument to finish both ends - driver and emulator.
Here is linux version latest builds

enjoy,
In fact the Agilent ICF (Instrument Control Framework) is a "kinda-kross-platform" layer written in .NET C# but it is highly tied with nice GUI binary dlls (hipster look-and-feel), so no way to make it platform independent. We also started a intermediate layer - .NET ICF application running on Windows serving instrument to network, but same story - no instrument, procrastination, lack of money etc
