Hi, one of the cron scripts seems to change access rights on /dev/ttyS1 once in a while to crw-r----- 1 root dialout 4, 65 May 25 19:40 /dev/ttyS1 (should have write access for dialout) Does someone know, which script does this? thank you in advance Ingo -- Ingo Hohmann, Otto-Speckter-Str. 17b, D-22307 Hamburg Tel/Fax: +49 40 69792480 email: ingo.hohmann@gmx.de
