| + | * The first audio Interface (line-in/out) is used for the GSM-Call audio. | ||
| + | * - Dialing os controlled via digital in 1 (in1) | ||
| + | * If it is set high (1), the predefined nummer is called. | ||
| + | * Must be set to high (1) to acknowledge incomming calls. | ||
| + | * Any call will be terminated when it goes low (0). | ||
| + | * - Incomming calls are signaled at digital out 1 (out1). | ||
| + | * It's set to high (1) when call is incomming and statys high during call. | ||
| + | * It will go to low (0) when the call is ended. | ||
