[gPXE] How does one view the DBGC messages

[Nathan Mitchell]

Everyone, 

      I'm fairly new to the gpxe code base, but I'm trying to use the HTTPS protocol feature. I've been running into a few problems and
 after examining the code, I saw that there are many debugging output statements littered around. How might one get those messages
to display? Is it the same as attaching the debugger over the serial/UDP? Or do I need to do something different?

    Sorry if this seems like a dumb question, but I can't seem to find any reference to the DBGC messages anywhere outside of gpxe's
code.
