ok you just connect the max in to system via serial port,connect MAX Tx pin to MAX Rx pin and open hyper terminal in to your system.
Type the character from your keyboard .Check,whether the character is displaying or not in hyper terminal.
if yes your MAX is Good.otherwise you have to replace MAX,before that connection checking is important.
