Earlier chips did support buffering, 1 byte buffering. The 16550 has a 16
byte buffer (often referred to as a FIFO - First In First Out)

This is NOT true. I have used 16450 and 8250 UARTS at 115200 before. The
trick is that it depends on the OS you are using. Windows tends to be pretty
sloppy in some aspects, depending on the speed of your system you may not be
able to get above 38400 with a earlier UART. However, you will easily
reliably get more than 2400 with one of these UARTs in almost any OS. TTYL
