Syntax terms

socket	Socket object
string	string
number	number is an op code indicating the type of web socket frame. Numbers 0-7 are non-control frames. Numbers 8-15 are control frames. Control frames are always sent immediately and cannot be fragmented. Specifying a reserved code will cause immediate request cancellation. 0 A continuation frame. A continuation frame is treated as text or binary based on the op code of the first frame. A continuation frame cannot also be the first frame. 1 A text frame. Text frames are are translated to ASCII with the translate table in effect for the port. 2 A binary frame. No translation is done for binary frames. 3-7 Reserved for future use and will cause request cancellation. 8 Connection close frame. 9 Ping. The receiver should respond with a Pong frame, unless a close frame has been received. 10 Pong. This is sent as a response to a Ping frame. 11-15 Reserved for future use and will cause request cancellation. 128 This value is added to the frame op code to indicate the final fragment of a non-control message. The first fragment may also be the final fragment.
boolean	Boolean value that indicates whether to mask the data with a masking key. The default is not to mask the data. Masking is done using an internally generated masking key.
