As I had already written, MiNT does not directly access the registers in
this case. It uses TOS 3.06 XBIOS functions, in particular Rsconf, to
access all serial ports that are made available by TOS. Of course you
can argue that *TOS* should check if the SCC is there, but -- well -- it
doesn't. Also, I don't think adding wrappers in the MiNT kernel around
XBIOS functions in order to catch bus errors is the way to go.
I'm quite confident that -- if required -- I could provide a test case
that does not need MiNT and that will crash at the same instruction
inside TOS 3.06.
