2.4.3 CLASS 1 DRIVER STATE MACHINE INITIALIZATION
The Class 1 driver utilizes a state machine for processing all requests. The requests to the state machine
llc1_request() are sent from the application as well as the network (other mode) itself. The state machine
must
ENABLE_WITHOUT_DUP_ADDR_CHECK is used to initialize the state machine. See the Class 1 Driver
Detail Description on how to request services from ControLink.
Example:
2.4.4 SAP ACTIVATION
Each
SAP_ACTIVATION_REQUEST service request to enable the SAP. This process is necessary so that
ControLink can determine which incoming messages have valid addresses and which ones do not.
Example:
To summarize, the entire initialization process is as follows:
be
/* use ssap and dsap of 0 for internal operations */
status = llc1_request(0,0,ENABLE_WITHOUT_DUP_ADDR_CHECK, &SAP0);
if (status == E_OK)
else
SAP
/* enable SAP1, use 0 dsap because it is a local operation */
status = llc1_request(1,0, SAP_ACTIVATION_REQUEST, &SAP1);
/*
enable group SAP1, use 0 dsap because it is a local operation
set group member of structure SAP1 to 1 to indicate a group SAP
*/
GSAP1.group = 1;
status = llc1_request(1,0, SAP_ACTIVATION_REQUEST, &GSAP1);
