[En-Nut-Discussion] Problems sending 0x0D data to a remote server.

[Javier Longares]

Hi all,

We have a system composed of an ethernut which sends and receives commands
and events from another board.  Each of these commands and events are
composed by headers, CRCs, etc.  When an event is received by the ethernut,
it must to check if the CRC is OK and then retransmit it to a remote socket
server. The problem has appeared when an event has the byte 0x0D, because in
this case the remote socket server receives 0x0A despite 0x0D.

We've checked our code and if the data is sent though a serial port the data
is transmitted OK.  So, as far as I know, the Internet Protocol has some
stuffing with the CARRIER and LINEFEED bytes (0x0d and 0x0a),  If this is
the problem I would know if this stuffing can be avoided indicating that
we're sending data bytes (binary) despite text or not.

Best regards,
Javier
