tocol. On the other hand, internal AT command is message with AT command string
sent from MMI task to ACI.
5.1. Enter command line mode of console daemon
Input one specific AT command “at$cons” to enter into console daemon com-
mand line mode. If command line mode changes successfully, hyper-terminal will
show “cmd%” string.
In this mode, the inputted character string is sending to console daemon (MMI
prototype). Then, console daemon task sends internal AT command to ACI or exe-
cutes specific command line function. For example, we defined one command line
function “cmd_if_audio_melody_start” to test correctness of audio driver API
“if_audio_melody_start”. Input command “cmd_if_audio_melody_start” and its argu-
ments (single space between arguments) for executing this command line function. If
this command is inputted correctly, melody will start playing. Otherwise, it will shows
“cmd error” string on hyper-terminal.
If we want to input internal AT command in command line mode, input “>” char-
acter and then it is available to input internal AT command. Input AT command char-
acter string and this string will be transmitted to console daemon task. Then, console
daemon task will send Internal AT command to ACI. And input “<” character to return
command function input mode.
