[Coco] NitrOS9 question

[David Ladd]

Dave,

Since I can't test this on a CoCo3FPGA right now I did finally get my
Deluxe RS232 Pak working.  I modified the make files for the NitrOS-9
project and made myself a CoCoSDC headless that uses the sc6551 driver and
term modules.  Here is my short ident of my OS9Boot file.  I tested it and
it does work and with the standard Shell+ as well.
