I am a new perl user and am having a problem with ioctl.  I'm running
on a Sun with SunOS 4.0.  The description of ioctl in the perl man
pages (i don't have the book yet) seems to imply using the packing for
the older version of ioctl (e.g. ccccs).  The Sun manual says it uses
the older System V ioctl structure for some calls but the structure is
defined as 4Sc8C.  The manual spends most of its space on discussion of
ioctl based on ioctls.h with a structure of 4L18C.  I am trying to do
RAW terminal io.  The work around using stty described in the most
frequently asked questions seem to work but I would like to use the
more elegant ioctl approach.  Anyone have any Sun experience in this
area?
