[Coco] Level 1 & Drivewire

[Neal Crook]

Hi Bill (Nobel),

I checked the Drivewire spec. and found that it calls for 1 start + 8 data
+ 1 stop and that 115,200bps is a supported speed.
I reviewed the UART RTL and ran an RTL simulation and confirmed that the
UART is hard-wired for 1 start + 8 data + 1 stop -- and the default
configuration runs at 115,200bps.

In summary, I was incorrect to indicate any hardware impediment. It seems
as though "all" that's needed is a version of dwio.asm that writes to a
6850-style UART. Are you interest in working on this?

regards,

Neal.
