 hello
in response to a readyRead() signal i check if a socket.bytesAvailable()
is non-zero at which point I do a socket.readBlock(maxbytes).  The
buffer returned is zero bytes long and  doesn't have any data in it.
As a test I followed the readBlock with a loop that makes calls to
socket.getch() which returns  valid data for the number of
bytesAvailable.
I can use getch()s if I have to, but it seems that readBlock should work
in here. What might I be doing wrong this time, I ask.
def HandShake (self):
    socket = self.sender()
    n = socket.bytesAvailable()
    if n > 0:
        hail = socket.readBlock(32)
        print "readBlock(): ", len(hail), hail        # -- hail is empty
        for i in range (n):
            print "getch(): ", socket.getch ()          # -- prints
valid data
thanks for any help
Michael
