I am trying to use the serial port to access a Lantronix mss100 via null modem cable - LL 5.4.
Using gtkterm, when I run the program I get a "permission denied" message. How do I gain access to the serial port?

*Edit* Solved - I had to add myself as a member of the "dialout" group. Now it is working.
