What problem you are facing in doing so??

Just use PIC Micro-Controller UART and RS232 Line Driver IC such MAX3232/MAX232 to send data on PC, instead of receiving on Hyper-Terminal program of windows, use MATLAB to receive data.

First of all you have to Open the Communication Port.

The Following Command Creates a Serial Port Object associated with COM1 and will set its Baud Rate = 9600 bps

Code:

 s = serial('COM1','BaudRate',9600);

Then you have to open this port, the command is as follow:-

Code:

fopen(s)

To Send a String to RS232 Port:

Code:

fprintf(s,'Sonsivri');

To Receive Data from RS232 Port in MATLAB

Code:

fgets(s)

To Close the Port

Code:

flcose(s)
delete(s)

I am also attaching some links with tutorial on MATLAB Serial Based Communication, apart from that refer MATLAB Documentation, everything is properly explained in that document.
