Advice and assistance on computer matters

just brought a cheap second hand laptop for my inpa and other diagnostic stuff, it has a serial port at the rear, I seem to recall that there was some sort of advantage in using the serial port but cant remember what advantage it was, anyone remember?
A proper serial port is required for early cars, which use ADS. The later cars use OBD-II signals and can be connected to using USB readers (this is true even on cars without an OBD-II socket, like my 01/99 car). I have not tried using a serial port to connect to later cars, but you will probably want to confirm that it works before buying a serial port reader.
