This is an eBay auction/sale for a diagnostic program that claims to work
for my E36, and many other models. My computer hasn't got two Serial Ports
on the back, but I suppose I could get another one and plug it in, assuming
I have an available slot on the motherboard.
I would be interested in spending the $60 for the diagnostic cable and
program if I had any independant assurance that it actually worked.
I can't imagine why two COM ports would be required, could anybody give me
some help on this?
