Console Display mode

[Jerry D. Pierce]

I have a Wyse VGA monitor hooked up and running Interactive 2.0.2
on a Wyse 386 machine.  I would like to be able to use the monitor
in the 80x43 EGA mode, but am unable to "toggle" the correct bits
using ioctl calls.  I would think that a "ioctl(0, SW_ENHC80x43, 0)"
would put me into the correct mode, however when this is called I 
go into "invisible console" mode.  :-(
 
I assumed (I know, a dangerous word) that I would be able to switch
modes fairly easily, from VGA on down to CGA...   Bad assumption?
 
The display(7) man page doesn't even MENTION vga displays.
(Luckily the kd.h files does...)
