Accessing /dev/ttyUSB0 to send SMS

[Herman (ISTD)]

May be sudo could solve this problem but not permanently, since sudo
only add root rights to user for certain period of time.
Is there any way to make devs such as serial line and USB controlled by
certain user ?
Another question, is it common to run nagios as root ?
Thx.

Regards,

Herman
