Dear All,

I am experimenting with an optical communication link. It is required to evaluate the link performance by symbol error calculation. The apparatus is setup such that I can transmit and receive data on my computer using two different serial ports via this link. My transmission speed is 921600 baud. Now I want to compare each transmitted byte with  each received byte using matlab.

So far I can:
1.open the two com ports in matlab
2.communicate at 921600 baud
3.transmit and recieve one byte at these ports

I am looking for:
1.to transmit 10 million bytes in bulk
2.compare byte to byte tx and rx streams
3.save different bytes in the streams in a separate array to decode the tx an rx bytes for determination of different bits

Which tool is best to do the job, a script file, a GUI or Simulink? Any code that can  help in that direction?
