       SEQFrame

SEQFrames are objects that represent the SEQ frames used in RFC3081 for the TCP mapping of BEEP. SEQ frames are used to tune the window size for sending and receiving over a particular channel within an individual TCP connection. This is one of the most useful and cool parts of BEEP.
Method Summary
  __init__(self, channelnum, ackno, window, databuffer)
  __str__(self)
  _bufferToFrame(self, data)
Converts a bytestring data buffer to a frame object.
  _checkValues(self, channelnum, ackno, window)
