You can certainly do this with the C++ version of FOX, using 
FXApp::addInput(). Under Unix you pass the file descriptor for your 
file, pipe, socket, etc. to addInput() to indicate that you'd like to be 
notified of asynchronous events that occur on this file. Similarly, 
under Windows you pass a kernel object HANDLE corresponding to the 
file/socket of interest.

This has been implemented in FXRuby too, but I honestly haven't used it 
enough to know how well it will work under Windows. One of the examples 
included in the FXRuby source distribution ("inputs.rb") should give you 
an idea of how to get started. If you do run into trouble and can send 
me a short example program we can probably get it to work.
