Re: laplink cable

The shell and pin 25 is the common ground. standard. if you want a
standard, follow what the parallel cable has already laid out.

quite a few places offer a db25 connector on a pcboard that has 25
screw terminals.

and althought you get 25 screw terminals, getting a 25 conductor
cable is not as easy. seems lots of manufacturers figure that you
are using it as a printer cable and make all the grounds common and
from my cables, seems some use one ground line and others use one
wire to each pin, then jumper the pins.
