How do I monitor for specific command line errors (Windows) ?

I need to have a batch file with multiple drive mapping statements like this: 

@echo off
net use Q: \\serve\share

When the drive is already connected, I get system error 85. How can I monitor for the 85 error and take my own action (like a cheap goto already_connected)? If it's any error other than an 85, I want to see the message displayed (or grab it from a variable and display it... whatever).

I've tried some samples I found, but I can't seem to suppress the system error display and I can't figure out how to trap specifically for the 85 error. If I could get a sample of how to do the error suppression, trapping, etc I can probably craft the rest of the code.

Thanks,

Instead of checking for error after map, check for map before error

edited to correct an error in existing map search

    call :doMap q: "\\server\share"
    ....

:doMap drive share
    rem search for drive map in server
    net use | find /i "%~1" | find /i "%~2" > nul
    if errorlevel 1 (

        rem if not found, test if drive letter is mapped
        rem and remove map if needed
        net use | find /i "%~1" > nul && net use "%~1" /delete >nul

        rem map drive to server share
        net use %~1 "%~2" > nul

    ) 
    goto :eof
