Sending 10 CRs in RS232 mode

I use AX2550 and I want to know if I send ten consecutive “Carriage Return� character to the controller which is already configured in RS232 mode, what will be the response of the controller, will it ignore this command or simply accept it and send back an acknowledge? what will be the acknowledge then?

Once it is in rs232 mode, the controller will echo whatever character it receives. So it will just echo back your CR
