About Digi Port Authority

Digi Port Authority (DPA) is a monitoring tool that dynamically displays the status of Digi serial communications products installed in UNIX systems, and may be used to perform loopback tests on individual ports.

DPA provides the following types of status information:

• Adapter configuration: the resources used by the adapter
• Port status: the state of each EIA-232 signal
• Port configuration: the state of stty and ditty flags for each port
• Host adapter status (C/X and EPC/X adapters only): various activity and error counters
• Loopback test: verifies functionality of the physical EIA-232 interface.  

This status information can be useful for troubleshooting an individual Digi port or to determine the state of a Digi adapter. DPA is installed automatically when the device driver is installed. DPA is character-based, and can be run from any terminal with access to the UNIX system.

To run DPA, change to the installation directory /etc/digicpci and enter the following at the command prompt:

./dpa
