* Nice Update of PPPD support which eliminates the
requiremetn that drivers be in the termios TASK_DRIVEN mode.
Mike did significant testing and reports that it seems to be
more stable and handle larger packets better. This patch
replaces the termios tasks with more general pppd network
driver tasks. The functions pppinput() and pppstart() get
called from the interrupt service routine.
* libc/termios.c: Added PPCDISC.
