bpptest Test Modes

Connection 

Yes 

In this mode, bpptest verifies that a bidirectional parallel port is configured on the system. The success of the bpptest in this mode indicates that the bidirectional parallel port hardware and the software driver are installed on the system.

Functional 

(Offline) 

Yes 

The testing done in this mode registers a failure if the port is found busy. This is because SunVTS tests make the assumption that all the resources will be available for testing in the Functional test and therefore the unavailability of the device is interpreted as an indication of a fault condition.
