I posted the original article. According to the messages at boot up messages
I have two 16550A's. However, I can't find anything in the booklet that came
with the board that mentions 16550A only 16550. It says:
"Compatible with the 82C550 and 16550 Universal Asynchronus Receiver
Transmitters (UARTs)."
