What is Actually Sent in a Message
Although you will send and read messages as strings of ASCII characters, the actual message
travels as a sequence of bytes. Each character in this sequence requires 1 byte. See example
below, which illustrates a “lamp limit is 2000 hours” reply from the projector.
