I think what he ment was someithing like this (off the top of my head)

open "temp.bat" for output as #1
    print #1, "DSZ rs 9600 etc etc etc.."
    print #2  "IF ERRORLEVEL = 2 GOTO FAIL"
    print #1, "IF ERRORLEVEL = 1 GOTO PASS"
    print #1, "FAIL:"
    print #1, "ECHO 2 > EXIT.DAT"
    print #1, "GOTO END"
    print #2, "PASS 1 > EXIT.DAT"
    print #1, "GOTO END"
    print #1, "END:"
    print #1, "EXIT"
close #1

SHELL "TEMP.BAT"

OPEN "EXIT.DAT" for input as #1
    input #1,E_LEVEL$
close #1
KILL "TEMP.BAT"
KILL "EXIT.DAT"

Print "Your errorlevel is =";E_LEVEL$

end

Got a little sloppy with my print #1's (they should have
all been #1, but a few #2's crept in there), anyway you get
the idea, havn't tried it but it should more or less work.
