Details
This routine will disable host communication and place the equipment in the "not communicating" state.
Before communication can be successfully disabled, the communication channel must be properly installed and configured and communications with the host must be established. All the configuration options for the serial or ethernet channel as well as the GEM parameters are set in the GEM Variables database.
The equipment constants that define the communication configuration and GEM parameters are included in Predefined SVs, ECs, and DVVALs. They are also summarized in Tables 4-1 through 4-3.
