Serial Communication Using fwrite or fprintf

Hello! I am trying to set up code to use the serial function to send communicate through the serial port. On page 31-33 of this manual: http://www.biopac.com/Manuals/fnir%20cobi%20manual%20v3i.pdf It says that I can send marker synchronization. There is a table that lists byte values for different markers. How would I send this through MatLab?
I already have this code thus far:
s = serial('COM3', 'BaudRate', 9600);
fopen(s);
What can I write to send the marker through?
Thanks for your help! You'll be alleviating a lot of headaches.

Thanks! This helps. I wasn't quite sure what I was supposed to put for 'A' in the MatLab documentation center.
