You probably need to set the speed; you might also need to set the line terminator.

MATLAB: Error Dialog Box for Serial Communication

Unfortunately the documentation of serial does not explain what happens, if the port cannot be opened. Therefore I guess:

try
  s_port=serial('COM6','BaudRate',115200,'Parity','none', ...
                'DataBits',8,'FlowControl','none');
catch
  errordlg(...)
  return;
end

Or:

s_port = serial('COM6','BaudRate',115200,'Parity','none', ...
                'DataBits',8,'FlowControl','none');
if isempty(s_port)  % or what ever, please simply test this
  errordlg(...)
  return;
end
