Folks,

I need to switch the VGA console to 132x25 characters.  I have
investigated how to do this and have determined that I should be
using ioctl(0,SW_VGA_C132x25).  Unfortunately when I try this I
get a return code of -1.  I assume my approach is correct as I can 
change to 40x25 etc (not that I want to).

I have tried this on an NCR System 3000/3445 running SVR4 1.03 and
also on my Esix SVR4.03 at home and neither of them work.

The NCR VGA diagnostics can change to 132x25 happily enough and running
my system at home on DOS lets me go to 132x25 also.

Is there a problem with Unix and its ioctl() approach?

I would really appreciate some help on this one.

Regards
