Do you understand what serial is/does? It's perfect for industrial applications, that's why most people haven't and won't try to get off the 232 or 485 standard.
Isn't USB just a very fast serial port? Why can't they switch all this equipment to USB? Some microcontrollers already use a USB interface.
Well, C# is better than C, why isn't everyone using C#?
It's an ancient, really solid standard. It will be around for much longer in industry.
I think the difference between C# and C is much greater than the difference between a serial port and a USB port.
I was hoping someone could elaborate a bit more on the technical aspect of it. USB has been around since 1996. Is that not long enough for it to be considered a proven, stable interface? Serial has obviously been around longer, but has it really improved much in recent years?
