[Gambas-devel] Parallel port

[Jean-Francois Perreault]

I haven't used gambas yet so I'm completely in the dark here , but 
wouldn't it be possible to use /dev/ttySx as a normal file to use the 
serial ports (and other devices) without the need for a special components

I mean if cat /dev/ttyS0 display all the raw input from a mouse all you 
need is a data parser and you can read mouse data , wouldn't it work ? 
maybe I'm way out on this but I'd like to know why
