Hi all folks, "Send a fax" works fine as ROOT ONLY. kprintfax works both on "Cups and LPRng". An OpenOffice document can be faxed direct with the "Print" command and the recipient receives a high quality fax. But "Send a fax" can't work as USER. With the same steps used as ROOT the OpenOffice document can't be faxed. During faxing a temporary text lock file is automatically created to lock /dev/modem Log file: .... .... efax: 32:49 created text lock file /var/lock/LCK..modem efax: 32:49 opened /dev/modem (hanging here) The modem is locked here $ cd /var/lock/ $ ls -al total 20 drwxrwxrwx 4 root lock 4096 May 24 18:23 . drwxr-xr-x 21 root root 4096 May 5 01:51 .. -r--r--r-- 1 satimis satimis 11 May 24 18:23 LCK..modem drwxr-xr-x 2 root root 4096 May 24 17:16 subsys drwxr-xr-x 2 uucp uucp 4096 Jul 20 2002 uucp $ cat LCK..modem 3930 # ls -l /dev/modem lrwxrwxrwx 1 root tty 11 Apr 22 12:24 /dev/modem -> /dev/ttyLT0 # ls -l /dev/ttyLT0 crwxrwxrwx 1 root uucp 62, 64 May 23 10:17 /dev/ttyLT0 I have tried sometimes without a resolution. Any folk on the list can shed me some light. Thanks in advance. B.Regards Stephen Liu -- Psyche-list mailing list Psyche-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/psyche-list
