Hi,

i have the following problem:
Everytime when I try to get access to the Serial Ports I get the feedback that
the permission is denied:
$ /opt/owfs/bin/owhttpd -d /dev/ttyS0 -p 2010 --foreground
DEFAULT: ow_serial_open.c:(38) [Permission denied] Cannot open port: /dev/ttyS0
Permissions problem?

$ ls -l /dev/ttyS0
crw-rw-rw- 1 Administrator Domänen-Benutzer 117, 2 31. Mrz 22:59 /dev/ttyS0

I don't know what I am doing wrong, so may I ask you for help?

Best regards
unix1970
