Okay, for my stupid question of the day ... we hooked a win laptop to serial console, run crt on it, boot with boot.config option of -P and took out keyboard. serial console works fine, hit ctrl-alt-esc and I get the Windows start menu coming up, not DDB debugger though ... read man page for boot, figured that -D option would get me to serial console/video, figured wrong ... anyone can suggest either software to use on the laptop or how to get into DDB through CRT? Oh, thought about the BREAK_TO_DEBUGGER option, but can't find a way in CRT to issue a break signal ... Thanks ...
