[Coco] NitrOS9 question

[Dave Philipsen]

Well, just for snicks I will try creating a Term descriptor for T2 and 
changing the default console in Init back to Term.  However, the 
'external processing' that T2 would need should come from SC6551. If you 
think about it, T2 is already working without VTIO because the sign-on 
banners show up.  That means that the I$Write system call is sending 
data to IOMan who sends it to SCF who then determines that T2 is driven 
by SC6551 and sends it to SC6551.

In addition, T2 works when VTIO is present even though there is no Term 
descriptor.

I would think you would want to use "term_6551" or "term_6850" (whichever would be appropriate) instead of T2 as these are serial terminals meant to receive from the acia and print to the screen. And yes VTIO would most likely be needed. T2 would some sort of external processing to send the data to the screen... hence why the serial terminals are used.

But, when I try to remove VTIO I get the signon message from Init on T2 but I don't get a shell.  To my knowledge VTIO is simply a device driver module for the SCF window devices.  If I have no window device descriptors in the bootfile, then, why is VTIO needed?
