wedged — HylaFAX modem wedged script
/var/spool/hylafax/bin/wedged devid device
bin/wedged is the command script invoked by the facsimile server when a modem is deemed to be in an irreparable state and requires operator intervention. This decision is based on the setting of the MaxSetupAttempts configuration parameter described in hylafax-config(5F). The default wedged script sends electronic mail to the FaxMaster alias. The interval at which emails are sent can be configured in the etc/FaxWedged file by setting the WEDGED_EMAIL_INTERVAL variable to the desired number of minutes (emails will be sent no more than every WEDGED_EMAIL_INTERVAL minutes, until the wedged condition persists). If the variable WEDGED_DISABLE_FAXGETTY is set in etc/FaxWedged then the script will attempt to disable any faxgetty processes spawned by the init(8C) process for the problematic modem. In addition the faxq(8C) process automatically disables use of the modem for servicing outbound jobs.
The devid argument is the identifier derived from the name of the modem's device file by substituting “_” characters for “/” characters; e.g. term_10 for /dev/term/10. The device argument is the name of the character special device associated with the modem.
If there exists an executable file /var/spool/hylafax/etc/resetmodem then that file will be executed (with the device name as the only argument) upon execution of the wedged script in an effort to recover the modem.
