I have just purchased the R/S ACIA RS232 card for my CoCo, and
I would like to write a device driver for it to replace /t1, which now
uses the same bit-banger as /p.

I can read the Tandy/Microware Technical Information doc, but that
takes me only so far.  Namely, I can't figure out how to get there
to a working, assembly language device driver module.  Now, UNIX
block and character device drivers have canonical forms, so that if you've
seen one, you can easily write a new driver for a new device.

Can anyone supply me with a similar boilerplate for OS-9 device drivers?
Does anyone know if Microware supplies more detailed documentation than
what comes with Tandy OS-9?

Thanks.
