Engine Connects to the DCSS Message Router |
|||||
| When DCSS is started, the Scripting
Engine connects to |
|||||
| the Message
Router twice. With one connection
it claims |
|||||
| that it is a
GUI client. With the other
connection it claims it |
|||||
| is a hardware server. |

Routing |
|||||||||||
| A request from BLU-ICE to move a |

| scripted
device is forwarded to |

| the Scripting
Engine by the |

| Message
Router. |
|||||||||||
| The Scripting Engine processes |
|||||||||||
| the script
associated with the |
|||||||||||
| device and
issues additional move |
|||||||||||
| commands to
the Message Router |
|||||||||||
| as the script
dictates. |
|||||||||||
| The additional move commands |
|||||||||||
| are forwarded
to the appropriate |
