If a control command is received while the device is in the midst of executing a previous
command, and the commands are mutually exclusive (cannot be executed in parallel), then
the previous command is aborted and the new one executed. It is up to the host controller
(the PC) to poll the device and make sure the previous command has finished, if that is
needed.
Query Commands
Query commands return a value to the PC as soon as the command is parsed and executed. The
value returned will depend on the command. The response is always terminated with a
“<CR><LF>”. If a query command is not recognized by the device, then a "?1" is returned.
