+ * The ipaq sometimes emits a '\0' before the CLIENT string. At this
+ * point of time, the ppp ldisc is not yet attached to the tty, so
+ * n_tty echoes "^ " to the ipaq, which messes up the chat. In 2.5.6-pre2
+ * this causes a panic because echo_char() tries to sleep in interrupt
+ * context.
+ * The fix is to tell the upper layers that this is a raw device so that
+ * echoing is suppressed. Thanks to Lyle Lindholm for a detailed bug
+ * report.

* Added support for the HP Jornada 548 and 568. Completely untested.
* Thanks to info from Heath Robinson and Arieh Davidoff.
