Sending binary data from Matlab to FPGA using the serial port

Hello,
In fact, I'm working on a project which aims to implement a 
reconfigurable Zigbee tranceiver on XUPV5-LX110T Evaluation platform 
which integrates a Virtex 5 FPGA. I am currently in the phase of real 
test, so now I just want to test my transmitter.
First, I want to send my binary data from Matlab (computer) to FPGA. The 
medium of communication is the RS232 serial link. Is there a solution in 
Matlab (communication protocol) that sends a binary stream on this port 
knowing my main entrance on FPGA is 4 bits?
Secondly, how to create a PRBS (Pseudo Random Binary Sequence) in Matlab 
(an output of 4 bits) to integrate it into the communication protocol?
And thank you in advance for everyone.
Regards,
Isamel

Is the computers interface able to handle that specific 
"4-bit-transmission"?
RS232 is a byte oriented interface. I don't think that your 
"matlab-computer" is able to transmit half-bytes.
You will have to wrap your specific data into your specific protocol. 
And you will have to decode that protocol in the FPGA...
