- * restore_loop - reattach the ppp unit to the loopback.
- *
- * The kernel ppp driver automatically reattaches the ppp unit to
- * the loopback if the serial port is set to a line discipline other
- * than ppp, or if it detects a modem hangup. The former will happen
- * in disestablish_ppp if the latter hasn't already happened, so we
- * shouldn't need to do anything.
- *
- * Just to be sure, set the real serial port to the normal discipline.
