RS-232 is the name of the "standard" (RS stands for "recommended standard")
that defines the low level electrical details.  USART stands for Universal
Synchronous Asynchronous Receiver Transmitter, and is the name of the PIC
peripheral intended to make it easy to ultimately communicate via RS-232.  A
PC COM port is a physical implementation of RS-232 on a PC.
