	ttynaming.h -- SCO tty naming decision
	[e-mail]

  You might want to change this (if you are on SCO, but have
  non-SCO style ttys, but then you have to be careful about
  using upper- versus lower-case tty names in inittab/utmp,
  Devices, dialing directories and interactive usage; some or all
  XENIX implimentations have problems with CLOCAL swapping to
  simulate upper- vs.  lower-case name choices, but that is too
  long a story to go into here :-< ...  you may need to omit
  SCO_TTY_NAMING under XENIX and watch your cases.  There are
  several uses of SCO_TTY_NAMING throughout the code but one
  common use has been localized in the TTYNAME_STRCMP macro
