I need a cable or wiring insructions, if possible, to adapt a 9 pin serial
computer port to an RS232 type male connector. The cable is needed for an
automotive diagnostic tool I have and is used for loading software updates
from my computer to the tool. The mfr. wants $55.30 for this thing and I
believe I can build it or find it cheaper somewhere else. Struck out at the
local radio shack. Thanks for any help.

There is no such thing as an RS232 connector, I assume you mean DB25
connector? Where does this diagnostic thingamajig plug into? Serial or
parallel port? The diagnostic tool has a 25 pin male connector, it's made for
a parallel port it sounds like.
