I have a laptop which has only one serial port. I went into: directory, and I found: How do I know which of those "ttyS" refers to my serial port?

Fix for: How do I know which /dev/ttyS* is my serial port?
Low Risk
I think it's this command: Running that on my own Linux box (which only has 1 Serial port) produces a single ttyS0 output line. Try it on your own, you will see what I mean.
