 I can verify changes to dz.c, sb1250-duart.c and zs.c with real hardware, 
but regrettably not right away: the hardware is in a remote location and 
while I have it wired for remote operation unfortunately its connectivity 
has been cut off by an unfriendly ISP.

 I'm not sure if all the changes make sense though: if there is a compiler 
warning or a usability issue, then a patch is surely welcome, otherwise: 
"If it ain't broke, don't fix it".
