[Coco] OS-9 Floppy / Printer configuration?

[Chad H]

Ok, I'm hearing X-Mode or T-Mode for the printer configuration and D-Mode
for the floppy configuration?  Is this right?

There's a utility out there called dmode that lets you modify RBF device 
descriptor modules (the ones in memory; you'll want to save them out to 
a file). If you don't have that, then you'll have to either create one 
with an assembler or use a program that will let you modify a file 
containing the device descriptors (and update the module CRCs). In 
either case, you will then want to recreate a boot file with the 
modified device descriptors.

For that you'll use tmode (the program that inspired dmode and its 
name), which modifies SCF flavored device descriptors.
