No problem with permissions. I am already the owner of the serial port.
That was the first thing I confirmed. I also have a script that runs on boot
to set permissions to serial and parallel ports. I use chip programmers on
parallel port and the serial port is used to talk to external boards.
In my office I also use a 2 serial/1 parallel port expansion board. I have
there 2 types of programmers there, one tied to a main parallel port and
another tied to the expansion parallel port.
