I am trying to create a script that will route data to/from stdin/out and a socket, without using fork() (Though there is preliminary support for fork() in the latest ActivePerl, I would rather avoid that route.)
I got select (IO::Select actually) to work great using two sockets, but select doesnt seem to like filehandles. So I tried this: 
while ( sysread(STDIN, $buf, 1024) ) || ( @ready = $sel->can_read() )

[download]
but that just blocks on the sysread(STDIN...
I thought about using the timeout option, but I don't want the script to pause in either direction.
FYI:
The end purpose for this script is to establish a connection for ssh (as the ProxyCommand). I am adapting a script written by Simon Josefsson to work on Windows NT.
Thanks for any help,
Glenn Harris
