An old thread I know, but I just noticed my desktop has AMT support and
was investigating if I could get access to the Serial Over Lan feature.
I stumbled across your HECI driver and thought I'd give it a spin. It
loads and attaches fine and unloads without issue as well. I tested with
device "HECI_DEV_ID_ICH9_82Q35" on a HP DC7800 minitower machine. I get
no output when I run your "heci-qst" program though.

Few more details:

heci0 at pci0:0:3:0:       class=0x078000 card=0x2819103c chip=0x29b48086
rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel(R) Management Engine Interface (HECI) (Q35-Chipset)'
    class      = simple comms
