[En-Nut-Discussion] Problem to connect a tcp socket

[Harald Kipp]

Julien,

No idea why the connect fails. I'd suggest to check this
with Ethereal.

But I can answer the question about port numbers. The
TCPSOCKET structure stores these values in network
byte order, not in host byte order. You should use
ntohs() to convert them. Beside that I'd use %u instead
of %d.
