SSL developed the Asynchronous Communications Tester on behalf of the HA as an additional tool for diagnosing problems with asynchronous communication links. 

It is designed to further extend the diagnostic capabilities of Tester for Windows with support for basic NMCS2 commands as well as custom messages for other link types. 

Fast poll, monitor, manual and slave based operations are all supported with an extensive array of performance statistics and hexadecimal debug output. A considerable number of configuration options are supported including standards serial settings, application timeouts and thread priorities.
