Hello Cheuk,

another way to issue JTAG commands through Altera programming adapters is to use the quartus_stp Tcl interface. The quartus ii scripting reference manual http://www.altera.com/literature/manual/tclscriptrefmnl.pdf tells how to. There's also an example Tcl script to read the IDCODE. Altera uses IR code of 6 for most (all?) devices to read IDCODE.

Regards and Happy New Year!
