These documents are not for the faint-at-heart. The contain detailed information about how to communicate with the Slink-e at the binary level. Most users will talk to the Slink-e using the SlinkX ActiveX control or Win32 high level C++ classes which don't require them to know any actual Slink-e commands. For those who want low level control or to use the Slink-e on a different OS, the following describes how to talk to the Slink-e. It is still recommended that user examine the C++ code to see a proper implementation of Slink-e communications. Slink-e communications can be broken down into two basic parts: commands sent from the host to the Slink-e and responses sent from the Slink-e to the host. Commands either modify Slink-e settings or send data to Slink-e ports. Responses report Slink-e settings, data received on Slink-e ports, or error messages.
