The W2 responds to commands for data supplied by the external system. Nothing is sent until a command is received by the
W2. These requests are in the form of a single letter as shown below. The user sends a single character and receives one data
string in response. The semicolon (;) is an end-of-string identifier, and will be at the end of every return string. The strings vary
in length. Use the table below to determine the output from your command input.
