Table 3 lists key software commands for the transceiver.
Detailed descriptions are provided in the SD Reference
Manual. Commands can typically be used in two ways:
1. The basic command (shown first) may be entered alone to
issue a query or execute a simple command.
2. The basic command may be appended with additional
arguments (shown in brackets, if applicable) to further define
a setting.
