That would be a somewhat rational explanation, but I don't use any input buffering (as most engine authors). Also PolyGlot has the same problem although I don't use stdio at all. It does not react to ^Z (it does react to ^D on Unix though, and so do all engines who test for EOF). In other words I don't know how to send EOF in a Windows command line. >Have a file with a single line > >xboard >Say x.inp. Run engine < x.inp.

In Unix it never matters whether one uses the console, a regular file, pipe, socket, etc... Fabien.
