[Coco] NitrOS-9 on a 128k Coco-3

[Bill Pierce]

Kandur, the post is actually about doing this in DW4. In dw4, it's all already setup, you just need the proper stuff on the PC end. I was never quite sure myself about that part. I know there's several here who use the Coco and NitrOS9 with dw4 through a terminal and can tell you more, but I don't know the specifics there. Since my Coco's a 1-meg, and Vcc is 2-meg, I have plenty of memory and run anything I need right on the Coco or emulator. I rarely play games myself... maybe a little King's Quest every once in a while, but more to watch the graphic techniques than to play the game.
I usually run a couple of text editors and my C compiler along with testing whatever project I'm working on.

Googled around a lot for "NitrOS-9 on a 128k Coco", and found this interesting 
article.

"This is content from the home.spogbiper.com website 
which ran on a CoCo during the 2010 RetroChallenge.

1/20/10 - The Headless CoCo
We've added support to use one of the virtual channels as the main 'Term' device 
in OS-9. This means you can run a headless CoCo and leave the drivers normally 
required for the CoCo's graphic console out of your boot file. The resulting 
memory savings are significant. This should allow a 128k CoCo to run programs 
that it could never fit into memory with the traditional CoCo console drivers 
loaded. The boot file can now be so small that it triggers an ancient bug in 
OS-9 that only occurs with tiny boot files. 
Boisy's looking into that."

Since I'm not interested in games and graphics, (including windowing) under OS-9
on my 128k CoCo-3, could someone help me out with such a boot image, where the 
default I/O would be the RS-232 port instead of the monitor and the keyboard?
I used such a setup for years, using commercial CRT monitors such as Hazeltine 
1520,
DEC VT100, Televideo 900 series. Oh boy, I've forgotten everything. (:
Or just point me to a good source of such info, please.
