But im a little bit confused as i have seen only those isp which uses the MOSI, MISO, SCK pins of microcontroller but the trainer i have is using serial port connections TXD and RXD for isp programming, how can this be can the controllers be programmed with just serial port and no isp connecttion ?????

    My bet is that the microcontroller has a bootloader in it.
