4.15. Configuring the Sending of the Proceeding Message

The application can configure if the Proceeding message is sent under application control (using the gc_CallAck( ) function) or automatically by the stack. The gc_SetConfigData( ) function can be used for this purpose. The relevant set ID and parameter ID that must be included in the associated GC_PARM_BLK are:

• GCSET_CHAN_CONFIG
  • GCPARM_CALLPROC - Possible values are:
    • GCCONTROL_APP - The application must use gc_CallAck( ) to send the Proceeding message. This is the default.
    • GCCONTROL_TCCL - The stack sends the Proceeding message automatically.
