Sorry but I find the above confusing. The best guess I can make is that
the 5 lines following >>> print data is the packet capture, and the 2
lines following "yields:" is the subset of the packet capture that comes
into self.data. Is this true? If so are you asking why
self.tn.read_until(self.host.upper() + "#", 7) does not get all the packet?
