Accessing /dev/ttyUSB0 to send SMS

[Herman (ISTD)]

Dear all,

I use gnokii to send Nagios notification. Gnokii need to access
/dev/ttyUSB0 in order to deliver message to Handphone. At present, I
need to set nagios user to root group in order to accomplish this task.
If the nagios user is not in root group, it could not access
/dev/ttyUSB0.

Previously when nagios user is not in root group, I tried to do some
workarounds such as : chown nagios /dev/ttyUSB0 but it didn't work. Is
there's any way to access /dev/ttyUSB0 without setting nagios user as
root group ?
Thank you.

Regards,

Herman
