I can confirm:

Stalk commands *do* show up in the Hijack button commands display.

But it is the intepreted (by the Hijack Kernel) value of the Stalk button code, not the raw hex byte value sent by the stalk.

So, if your Stalk is out of whack (2 digit hex value wise) then the stalk codes generated by the kernel may not show up correctly (, or at all in some cases) and then the only way to know whats being sent down the wire by the Stalk is to attach a serial device to the Empeg serial port and see the stalk debug info when stalk_debug=1 is set in config.ini
