I don't know for certain... as I said, I didn't pick the code apart.  In fact,
my statement above is just what a cursory examination seemed to be saying.  In
any case, error messages are showing up under MGR in a window whose
controlling terminal is a pty... so TIOCCONS would likely not work regardless.
I suspect that you could arrange to grab error messages and either bit-bucket
them (since they get put in /usr/adm/messages anyway --- not that I recommend
this) or redirect them to someplace less annoying than a window-splatter, like
a special reserved "error window" like MGR does.
