serial port usage

i just want to transmit and receive data from a terminal on another for that i made a small code as follows

 global gnCount
  serial_comA = serial('COM10');
  serial_comA.Baudrate=9600;
  % gnCount=0;
   %set(serial_comA,'BaudRate',9600);
  % serial_comA.terminator='LF'

   serial_comA.BytesAvailableFcnMode='Terminator';
  %  serial_comA.BytesAvailableFcn=@fn_add_temp;
  fopen(serial_comA);

while(gnCount<10)
    disp(gnCount)
    serial_comA.BytesAvailableFcn=@fn_add_temp;
end
disp('finished')
    fclose(serial_comA);

% while(1) 
% if strcmp(serial_comA.status,'closed')
%  fopen(serial_comA);
% end
% end

and am getting as output when i run it but i want to receive ata from another pc

You have a "while" loop that depends upon gnCount, but you do not change gnCount in that loop.

Hint: you could use a "for" loop instead of a "while" loop.
