Class ShowPorts

java.lang.Object
  ShowPorts

public class ShowPorts
extends Object

Show the standard computer interfaces available to Java applications.

This application determines and lists the serial and (if supplied by the underlying libraries also parallel) computer interfaces available to Java and Frame4J applications on the platform used. Their state is displayed, too.

Hereby the successful installation of any combination of

• SUN's Java Comm extensions (commApi, not for Windows!),
• the RXTX extensions or of
• Frame4J'SerNimpl- / WinDoesIt implementation (serial only, Windows only)

can be tested / verified.


Hint: Hint this application does run without any of those extensions as well as when those are not correctly installed (missing dll e.g.). In those cases useful error reports are generated. On the other hand a re-translation and re-deployment of this application requires the (correct) installation of the the extensions mentioned.
