This program is available in the PDK as pdktest.c in the etc/pdktest directory. pdktest demonstrates how to start worker threads and how to us the eCos Control API to remotely control the worker thread. The worker thread simply makes a log entry at a user configurable interval. The application options in wxpxscontrol allow you to start, stop and query the state of the worker thread and to change the log entry interval.
When executed on the PXS, the following output appears in the remote log server's log file:

This session shows where the worker thread was stopped and restarted using wxpxscontrol, and finally, where the program was halted in preparation for rebooting to PXS.
