This is an example for standalone-operation with 2 errorlevel events defined. Event 1 returns level 10, event 2 returns level 20. No echomail and netmail is used.

       :Loop
       PROBOARD -S
       if errorlevel 100 goto End
       if errorlevel 99 goto End
       if errorlevel 20 goto Event2
       if errorlevel 10 goto Event1
       if errorlevel 1 goto FatalError
       goto Loop
       :Event1
       echo Perform some actions
       echo --------------------
       goto Loop
       :Event2
       echo Perform some more actions
       echo -------------------------
       goto Loop
       :FatalError
       echo FATAL ERROR - ProBoard Down
       :End

Using ProBoard with a frontend-mailer is a little more complicated. This is an example for use with FrontDoor.

In this example FrontDoor uses the following errorlevels:

 300 bps call : 50
1200 bps call : 51
2400 bps call : 52
Local call    : 60
Mail received : 100
Exit          : 150

  
       SET FD=C:\FD
       :Loop
       cd \fd
       fd
       if errorlevel 150 goto End
       if errorlevel 100 goto MailRcv
       cd\pb
       if errorlevel  60 goto Local
       if errorlevel  52 goto Call2400
       if errorlevel  51 goto Call1200
       if errorlevel  50 goto Call300
       :FatalErr
       echo FATAL ERROR
       goto End
       :Call300
       proboard -b300 -p1
       goto CheckPBErr
       :Call1200
       proboard -b1200 -p1
       goto CheckPBErr
       :Call2400
       proboard -b2400 -p1
       goto CheckPBErr
       :Local
       proboard
       :CheckPBErr
       if errorlevel 100 goto End
       if errorlevel 5 goto NetEcho
       if errorlevel 4 goto EchoEntered
       if errorlevel 3 goto NetEntered
       if errorlevel 1 goto FatalErr
       goto Loop
       :NetEcho
