    there is no such thing. I guess you mean "I am trying to program via the standard serial interface".

    most likely causes
    your MAX232 connections are incomplete/wrong
    you do not have sufficient chip decoupling
    you have a faulty reset
    you are using the wrong RS232 connections
    you are using a cheapskate USB to serial converter
