Well, I must admit you are right (once again). I don't agree with Joes statement that 9600 is default. I just now have a memory enlight. I was also not able to write on the RPIs UART port until I disabled the hardware flow control. Found out that for the UART it doesn't matter if soft/hard is enabled or not.
