what is the exact chip on your 232 board, is it MAX232EPE as this is a 5v chip and not the required 3.3v (really this is why i made the recommend tools sticky you could have save all the trouble and money)

anyways data tx to txd-isp, data rx to rxd-isp, gnd(any) to gnd-isp, 3.3v not connected so power the max232 via an external 5v power supply
