PPPd on rtems 4.5 beta1c

[Thomas Doerfler]

Hi,

I reworked the sources from Tomasz and integrated them into my 
current project. I plan to feed them back to the RTEMS project but 
some cleanups are still outstanding.

Here is what I did:
- added line discipline support for termios
- added task-driven serial I/O model to termios
- split the hardware-independent parts from Tomasz's modem driver 
apart, so any serial driver (based on task-driven termios) can handle 
PPP
- added some makefile support

Currently I still have one problem in task-driven termios concerning 
multiple close/open sequences on the same device. I think this is no 
big bug, but I had no time to fix it up to now.

I was glad to start with Tomasz's sources, but some parts were a bit 
confusing...

I had no big needs for customization, my system is working as a 
client directly connected to a WindowsNT Server :-(( so there were no 
big dial-in scripts etc.

Bye,
	Thomas.
