Should I grab the iron and change pin 1 to 7?

I suggest you find out what's wrong and fix it the way it's supposed
to be.. 

That'd require schematics ;)



Depending on config of the system chasseie ground and signal ground
might be isolated.

The only ground connected is shield ground. ;)


If there is a "klinik" (another DB25 port, or if it has DB25's for
user terminals (check if there is a board connected on the able)
measure from pin 7 to pin 7 in another connector.

Pin 7 is NCL on all the serial breakouts I have.


My guess is that someone has "fried" the console ground wire with
current, and you should be lucky more stuff is not dead. -:)

Possible ;)
