Are you using Python 2.3? Prior to 2.3, 'x in y' would throw a TypeError if
y is a string and x is a string longer than one character.
Is it working sometimes but missing sometimes? If the brsq spans an
8192-byte boundary you will miss it.
Are you sure the brsq is in the data sent? Maybe it has just a newline
terminator, or a space after the \x71 or some other difference from what
you are expecting.
