The data used to display information in the LCD alphanumeric display is in
ASCII format. If the telephone is not in use, the display normally shows the
date and time. The content of the display is changed automatically (e.g.,
receiving an incoming call, making an outgoing call, or activating a feature).
The Dialogic
®
PBX Integration Board can retrieve the information on its
alphanumeric display using the d42_display( ) function. The function places
the display data (48 bytes) in an application buffer. Refer to the Dialogic
®
PBX Integration Software Reference for more information about using the
d42_display( ) function.
Example
An application uses the dx_dial( ) function and the appropriate dial string to
press keys dial extension number 1045. The d42_display( ) function is used to
retrieve the display data and place it in an application buffer (shown below).
The information for the top row (first 30 characters) of the display is checked.
Data in bytes 00 through 03 indicate that extension 1045 is being dialed.
