TITLE: #228 - "AT+FBU=1"/"AT+FBUG=1" command rejected: ERROR KEYWORDS: AT+FUG +AT+FBU modem error RELEASE: Faximum ELS/PLUS 2.21 and v4 CLASSIFICATION: All PROBLEM: Customer is using a modem that is not on Faximum's recommended list and encounters one of the following error messages (depending on the make and model of the modem being used): AT+FBU=1 command rejected: ERROR AT+FBUG=1 command rejected: ERROR CAUSE: By default the Faximum server software enabled special trace reporting to assist with the diagnosing of modem problems. Unfortunately not all fax modems support this command. SOLUTION: Edit the fax line configuration file for the specified line and add a line of the form: fbug = no This will cause the fax server not to issue the AT+FBU or AT+FBUG command. NOTE - the fax-line configuration files can be found in the following directory: Release Directory 2.21 /opt/faximum/dev/fax-line-1 4.x /var/faximum/dev/fax-line-1 If you have more than one fax line then the other fax lines will usually be named fax-line-2, fax-line-3, etc. TechNote: 228 - Copyright 2001 Faximum Software Inc., All Rights Reserved.
