NOTE: The application can obtain the least significant byte of the value
returned by the d42_indicators( ) function by ANDing that value
with 0x0f.
Pressing Memory Keys
The Dialogic® PBX Integration Board can “press” any of the M7324 Memory
Keys using the dx_dial( ) function. Refer to the Dialogic® PBX Integration
Software Reference for more information about dialing programmable keys.
Each Memory Button on the M7324 telephone is assigned a dial string
sequence (refer to Table 26). By using the dx_dial( ) function and the
appropriate dial string, the Dialogic® PBX Integration Board can press any
Memory Button.
4.5.5. Display Keys
As shown in Figure 12, there are three Display Keys located below the LCD
display. These keys are associated with specific prompts shown on the LCD
display depending on the current state of the phone (shown on the bottom row
of the LCD display).
Reading Display Key Prompts
The Dialogic® PBX Integration Board can determine which of its prompts are
currently displayed by using the d42_display( ) function to retrieve display
data and read the information for the bottom row (last 16 characters). The total
length of the display data is 32 bytes. The data location for the Display Keys is
as follows:
Display Key 00 bytes 16 - 20
Display Key 01 bytes 22 - 26
Display Key 02 bytes 28 - 31
Refer to the Dialogic® PBX Integration Software Reference for more
information about using the d42_display( ) function.
