What does "won't work" mean? I can't see any issues in the code.

I suppose the string sent with 9600 tells the device to change the 
speed. Are you sure that it is received correctly?

Additionally, maybe you have output issues. E.g. you just write 
"ser.baudrate" instead of "print ser.baudrate", so that could be a 
source of behavioral differences.

I suppose this doesn't belong to the problem?
