[Coco] VCC Experience

Fri May 23 22:46:55 EDT 2014

Well, after a little makefile searching, I found what I needed.  I played with telnet to my raspberry pi,  for a bit, works good except vt100 codes are coming through so ‘ls' breaks telnet with error 208.  But essentially I found the code in the current Nitros9 repo for net.as library to do what I need.  The DriveWire docs are stated out of date so it took a little bit, to jump from those docs and Bill’s help to reach what I need.
