[Mono-dev] SerialPort auto-inserts carriage return

Im using a System.IO.Ports.SerialPort to communicate with an embedded system
currently being developed where i work. The ES uses a binary protocol, so
the data is not ascii and do not use newlines.
The strange thing is this; For every byte with the value 10 (linefeed) an
extra byte with value 13 (carriage return) is inserted into the stream im
reading from, totally messes up the protocol.
So: <10> becomes <13><10>, and also <13><10> becomes <13><13><10>.
I'm running Linux, the code has not been tested using .NET
Some of my code:
SerialPort serialB = new SerialPort()
serialB.BaudRate = 115200;
serialB.DtrEnable = true;
serialB.PortName = "/dev/ttyUSB0";
serialB.ReadTimeout = 5;
byte data = new byte[serialB.BytesToRead];
serialB.Read(data, 0, serialB.BytesToRead);
I'm thinking this is either a bug or there is some setting which turns this
off. Appreciate any help, thanks!
