Altera JTAG problem

Hi all,

I need help.
How to send single instruction/command thru JTAG interface with altera 
tools. I have to send FACTORY instruction and I know binry code for this 
instruction but I don't know how to send it.

Or in other words I have to reenable jtag interface blocked because of 
anti tamper feature ( in my design )
Please help.

BR

It ain't gonna happen with Altera-provided tools.

I would look for a general purpose JTAG tool, one with application-
level support.  Something like this: <http://www.amontec.com/>

I solved my problem with Altera support.
Funny is that when flash contains valid image - jtag is almost  disabled 
in ep3cls family. Only few commands are working.
