The DPA for Windows application provides a means of testing and monitoring the state of serial ports configured on your system. DPA for Windows runs under Windows XP, Windows 2000, Windows NT 4.0, and Windows 95/98/Me.
DPA for Windows provides a tree view of system serial ports, allowing you to choose specific ports to monitor. For supported Digi adapters, DPA for Windows displays adapter-specific information and a summary view of port activity on the entire adapter. Within DPA for Windows, you can open a terminal window for each port you choose, set port properties, send test data, and monitor port activity.
DPA for Windows includes online help that explains details of its display and controls.
