hai
Thanks for the link.
This is a serially interfaced JTAG.
Is their any substantial inconvenience or reduction in any type of speed or anything assocoaited with a JTAG interfaced through serial port other than a USB JTAG?
Which one you will suggest for me?
Difference in cost is around 10$.
Your opinion please

AVR JTAG interfaced through serial port works just fine.
The USB variant was developed mainly due to legacy PC COM port.
There is no penalty regarding speed using AVR JTAG interfaced through serial COM port. Or at least I didn't noticed.

Not much devices are supported by ICE.And no support will be implemented for newer avr's. Visit atmel page for device list.
If you plan to work with newer avr's - buy usb based ICE II . It supports debugwire as well (one wire debugging for tiny models )
