User use of Serial Ports

[Mickey]

Fedora 21/ KDE

I'm trying to run a App called apmplanner2 but it is not giving the user 
jim permission of using the serial ports.

the user owner of apmplanner2 is  jim.

When I try to run apmplanner2 I get a error message saying to run "sudo 
adduser jim dialout"

And the I get linux error on usage of adduser, something like adduser -D 
but that still does not work.

What am I not doing right ?

I've not used serial ports in a very long time.  However, I seem to recall needing to add the user name to the dialout group in /etc/group.  Of course you'll need to logout/login for that to take effect.

"sudo usermod -G dialout jim" should give user "jim" the auxillary group
of "dialout".

The way to check is "sudo cat /etc/group | grep dialout" and verify
that "jim" is in the list of users at the end of the line (after the
last ":" mark).
