That's what I tried already. It simply echoes the ^Z (right arrow).
I tried also to close the pipe explicitly from the sender side without
I'm afraid we're looking at a problem with more.com waiting until the
process releases the pipe. Closing the handle from one side of the pipe
isn't enough to close the pipe. Or as

instance of a pipe is always deleted when the last handle to the instance of
the named pipe is closed".

how about sending the ^Z line the CRLF is being sent to indicate line
that should indicate the EOF which should trigger the ending of the process
closing of the pipe... shouldn't it?
