[WINTCL] pipes

[John H H. <jhh...@un...>]

I am trying to use a bidirectional pipe to communicate with gnuplot.exe 
<http://www.gnuplot.info/> under ActiveTcl on Windows XP. This gnuplot 
executable works fine from cmd.exe or my Bourne shell, but not tclsh. 
The Tcl documentation for [open] warns of problems due to contention for 
stdin and stdout. I tried  to circumvent this by using wish, and am half 
way there, the problem now is that the readable-event handler only gets 
called on eof.
