PBX Integration Board can determine the state of its LED

indicators on the Function keys by using the d42_indicators( ) function to
read the LCD indicators data. This function places the LED indicator data (26
bytes) in an application buffer. Bytes 18-23 (excluding byte 20, which is not
used) contain the LED indicator status for Feature keys (see

Table 37

). Refer

to the Dialogic
