>Hi all,
>
>I have a situation where an (old legacy 2.x) app is setting up a network printer with a NET USE command, and we're also trapping for an 1102 error during a COPY FILE MyFileName TO LPT1: command. It seems to me (in the dark reaches of my feeble memory) that the NET USE command once contained a TIMEOUT clause or some such -- but it's not in the current docs anywhere.
>
>Anybody remember how to do this, or know another way to set the TIMEOUT of a NET USE?

>TIA,
