shell

[Guest]

I have been using the shell feature in PBDOS to net use printers
and copy files to printers ports. Examples.

NET USE LPT1: \\MAIN\CHECK >NUL
COPY /B Z:\CHECK.TXT LPT1: >NUL

The >NUL is to discard any messages from the net use or copy.
Without it you get message displayed on the screen

We are trying to run the programs unders windows/nt/2000 and the
>nul does not always pick up the message coming back.

Is there any way around this, or should i just save the screen
and restore it after the shell?

Output redirection only covers output that is sent to stdout, the standard DOS output
device. It is also possible to redirect stderr, the standard DOS error output device,
but some arcane twiddling is required. If output is being done in any other fashion,
it will not generally be practical to intercept it. COPY probably only goes through
stdout and stderr. What NET does may be another matter.

In brief, you might be able to do it by redirecting stderr. Saving and restoring
the screen would be a more general-purpose solution, though.
