Re: [Vala] Serial port help

[Ed Schouten <ed 80386 nl>]

Hello guys,

I've attached a working Termios binding to this message. Just run valac
--pkg termios and you should be able to use the Termios namespace. Below
is an example:

using Termios;

| class Test {
| 	public static void main(string[] args) {
| 		Termios.Termios a;
| 
| 		a.getattr(0);
| 		a.oflag |= OFlag.ONLCR;
| 		a.setispeed(Speed.B38400);
| 		a.cc[VKILL] = 'a';
| 		a.setattr(0, AttrType.NOW);
| 
| 		Termios.Termios.flush(0, FlushType.IFLUSH);
| 	}
| }

I'm not so happy with the namespace and the class having the same name,
but ideally we should introduce a `POSIX' namespace, which should
contain all POSIX (not ISO C) stuff.

Have fun!
