[svlug] serial ports

[Howard Susman]

In old old Linux, I had no trouble using serial ports for communication. 
Then maybe ten years ago serial ports did not work for me. I never 
discovered why. My solution was to stick with an old version of Linux.  
I chose and still am using Fedora release 6. Kernel 2.6.22. I could 
still use all my serial ports under that version. Still on Ubuntu 14.04 
LTS my ports did not work. The system did recognize them, but I could 
not use them.  For some reason, I gave it a try under Ubuntu 15.10.  My 
ports are back! It is the same code I used under older versions. I am 
happy and thought I would share my finding.
