Command Details
This section describes the format of all the command strings accepted by the module. Please note that
numeric arguments of command requests are mapped to upper-case letters (see above section).
Some commands share the same lower case letter, because there were no command identifiers available
when the protocol has been expanded, but the first argument is used to discriminate.
