Writing short MS DOS batch (.bat) file for Windows XP and need to test result of NET USE.

Here's the pseudo-code of what I'd like to do...
NET USE | FIND "LPT2" --> Put Result Into LPT2-OK variable
   THEN Issue Command
   ELSE Issue Another Command

Open in new window

What bat code would accomplish this?

How about something like this:
@echo off
net use | find "LPT2" >nul && "your-command-if-lpt2" || "your-command-if-not-lpt2"

Open in new window

To see this work, try the following:
@echo off
net use | find "LPT2" >nul && echo LPT2-OK || echo No LPT2

Open in new window

Or you could go for the traditional IF-statement like this:
@echo off
net use | find "LPT2" >nul
if %errorlevel% neq 1 (
    echo LPT2-OK
) else (
    echo No LPT2
