In the below example, we used errorlevel 171. In the batch file that runs the front-end mailer system, the error levels are listed in reverse order(highest errorlevel is at the top of the batch file), and should be set as follows to run BGFax: IF ERRORLEVEL 171 BGFAX /FCO C:\IM\INBOX 1 Here is what the parameters mean: Errorlevel 171 The errorlevel in which the front-end mailer exits with, upon a "+FCO" Class 2.0 fax connect /FCO The name of the software to send/receive the fax.
