In answer to your question:
	If the system has crashed, it would probably be impossible to talk to 
it to tell it to reboot.  Therefore you would need some external way to toggle 
the reset line in the chassis.  One of my hardware-hacking coworkers 
connected a device to one of our vxWorks systems that toggles the reset line
if the phone rings more than 8 times in the lab.  This is hardly an elegant
solution, but in order to remotely reboot the system you will need something
analogous to this.  If you are creative you can probably put some sort of 
device on whichever host your vxWorks system boots off of to accomplish 
the same thing.
