>> If I recall my 1970's hardware stuff, the "S" is important. UARTs synchronize themselves with start and stop bits, each character asynchronously triggered by the start bit. USARTs are not so lucky, and depend on other characteristics of the data stream to sync up (flags), and put characters back-to-back. No start or stop bits for them.
