Power off.  Power on, dock into cradle.
Comes up.  Displays 'Press Q...' on the screen.  Displayed boot banner to
serial port and screen, up to RedBoot>.  Without touching serial or screen,
wait, screen blanks.  Press enter on serial terminal a few times.  No response
on serial port, screen remains blank.  Touching the screen gives the standard
blink, then accepts touchpad input, but not serial input.

This is repeatable both with and without hardware handshaking.  Terminal
is w2k advanced server HyperTerminal.
