I see that the documentation is lacking in telling what the protocol version is. I'll see that that is added to the next release.

The version is the iteration of the WSMCom interface, which is currently 1. Your call would be:

BinaryWrite[socket,{1,1,0,0,0,0,0,0}]

Attached is a quick and dirty implementation of the basic functionality of the SCS protocol in Mathematica. It covers setting up the connection and evaluating a few commands.

Obviously you would like to add some more failure handling if used for more than proof of concept.

Attachments:

The correct thing to write would be BinaryWrite[s, {1, 1, 0, 0}]

• Protocol version: 1
• Packet type: 1
• Packet specific: 0
• Payload length: 0

However after some testing I suspect that BinaryWrite interprets it as string data, when I send the above the simulation interprets it as protocol version 49 (ASCII code for 1). Perhaps someone that knows more about SocketConnect can chime in.

In what language do you want todo this? Perhaps I can give you an example in a language that is closer to what you intend to use?
