Ian,
Yes, this example assumes that data is read from the computer's UART one byte at a time. From a software standpoint, this is the easiest case to deal with. If your computer's UART has a FIFO buffer on the output, and you get packets larger than one byte, the code (state machine) gets just a little more complicated.
