Serial port reading and writing character substitution

I'm using a TWR-K64F-120M Tower Module together with a TWR-SER module.

 

I'm running the Ethernet to Serial demo, but have noticed there is some character substitution occurring. Depending in what direction you are going 0x0D to 0x0A etc. I've tried changing the serial port open mode to "rb" and "wb" without any success.

 

How can I stop this substitution from occurring?

 

Kind regards

Roger
