/*---------------------------------------------------------------------------*
*
* history:
*
* -hm moving fd for default device from 1 -> 0 for such things
* as "scon -p list | more" to be possible
* (reported by Gordon L. Burditt, gordon@sneaky.lonestar.org)
* -hm adding option "a" for just returning the type of video adaptor
* -hm removing explicit HGC support, same as MDA ...
* -hm vga type/family/132col support info on -l
* -hm force 24 lines in DEC 25 lines mode and HP 28 lines mode
* -hm fixed bug with 132 column mode display status display
* -jw added 132/80 col mode switching
* -hm removed -h flag, use -? now ... ;-)
* -hm S3 chipsets ..
* -hm Cirrus chipsets support from Onno van der Linden
* -hm -m option, display monitor type
* -hm bugfix, scon -c <screen-num> cleared dest screen, fixed
*
