      Dear,
      I attached here the typical IC schematic, you should connect the same.
      the TXD pin of PC must connected to pin 13
      the RXD pin of PC must connected to pin 14
      then short circuit pin 11 and 12.

      ISA it must be worked.
      Regards,

      i am trying to connect atmega16 with computer through serial port cable
      and MAX232 and unable to do so
      I am following instuctions written in Avrbook. First step of short
      circuiting Tx and Rx pin of cable (without any other connection), i get
      values in HyperTerminal.
      Now second step of connecting cable to MAX232 and then short circuiting
      11 and 12 pin, i am getting nothing in hyperterminal. I have already
      tried 4 Max232 ICs but no output.
      On every site same diagram of connection is given, i have cross checked
      my connections several times.
      Plz help.
