[En-Nut-Discussion] Timing and Receiving Data Problem for TCPServer

[Jose Vicente Sanchez Ortega]

Hi, Clemens:

I totally agree with you. There's no relationship between the way the bytes
are grouped on the output stream and the way they are received on the input
stream. Any way, it looked to me that John was saying that the order of the
bytes on both input and output streams could be different and that was which
I didn't agree.

Thanks and regards.


Jose Vicente.
