`Serial connectivity' with something other than sio*?

[Garrett Cooper]

Hi guys,
	With more motherboard vendors venturing away from RS232 serial ports  
to firewire, I was wondering if anyone has ever configured either a  
firewire or usb to serial / usb adapter between two machines to  
emulate a serial console. This is a question I'd like to get an answer  
to so I can start working on a means to indirectly access boxes for  
the FreeBSD project to avoid the kludginess of manually testing  
things, or at least manually power cycling devices and booting  
targets, whenever possible. The chapter I'm referring to in the  
handbook is: <http://www.freebsd.org/doc/en/books/handbook/serialconsole-setup.html 
 >.
Thanks!
