Hello all, I was told this was the place to ask this sort of thing.
I want to programmatically write debugging messages to the Intel AMT virtual/fake serial port from within Intel TXT. So I can't use the AMT library.
The port shows up as COM3 in Windows (the only COM port). Is there a way to look up what the port IO port should be so I can use assembly to talk over it? I know that historically, by convention serial port 3 was at port 0x3E8, but writing to that (or any of the other conventional serial port addresses) doesn't seem to produce any output on the listening side.
Thanks in advance,
