serial port & ldisc: need help

Hi,

I need informations about line disciplines (what are they, how to use them)...

Is there anyone who could explain this to me ?
Or, is there any doc/book about this subject ?

The doc provided with the kernel is too small.

Thanks, roms.

I've seen no good documentation on this one. The ldisc is basically the glue between the serial layer and whatever is above

So its

	/dev/ttyFOO --- [LDISC] --- Serial

or

	/dev/ttyFOO -----}
        ppp0    ---------}--[LDISC] -- Serial
