We have gotten a little farther. This is what my friend wrote:

It is booting TTYA to the modem port as we suspected.  My dads terminal is 
able to communicate with it where as my FreeBSD is not.  I can now command 
your computer with my terminal keyboard!!!  Now the only problem is its 
saying invalid sector on boot disk panic!  <--- I have no idea what that is 
but I'm going to make a new disk I think.

Is this the right step? I will be at my friends house tomorrow to help 
(hopefully) install netbsd because we have it communicating to something. 
Unfortunatley when we try a serial connection to the printer port and try the 
ttyb it just says unknown word. Any suggestions? Will the terminal be fine to 
install netbsd? 

Thanks for everything,
Fedil
