3.7Setting Global Characteristics with the Individual Banks

Several other system-wide options are specified not by the system switch banks, but rather by the eighth switch position of the individual port switch banks. Explanations and tables are given below.

Self-Test Function

NOTE

The COS II can perform a number of self-tests that check the memory, the LEDS, the DIP switches, the ports, and the interrupt circuitry of the Switch.

More information about the self-tests is given in Section 4.8.

For	Set SWA 8
Normal operation	OFF
Self-test	ON

Sending or Suppressing Breaks

We recommend that you run software flow control from your application during self-test.

You can set the COS II either to pass break characters along or to block them from reaching your devices. SWB 8 controls this function.
