Le SCSI n'a jamais été installé en standard sur les PC en externe. Il fallait rajouter une carte.

Then why did I have one

Cette interface aux nombreux défauts a été remplacée avantageusement par l'USB.
Par contre, l'USB n'a pas la possibilité de réaliser tout ce que fait la RS232. L'abandon de cette dernière est donc problématique pour certaines applications très spécifiques.

For that you dont need a 190 Euro docking station for that a 12 Euro USB to COM converter will do

No, It don't.
Because the USB interface can't be master and slave in the same time. So, it's impossible to use USB for some applications (with or without converter), especialy for the two-way communication with PLC or other selfmade electronic makings.
The closer actual interfaces to do that is the RJ11 or the RJ45 but it's more complexe to acces it via program, the protocol is more complexe than that of the RS232.
RS232 is the paradise of the tinkerers.
