Using the Utility
The VGAMODE utility program allows you to specify the
number of rows (lines) and columns on the screen. You specify
these values in the VGAMODE program by typing them on the
VGAMODE command line.
The format of the command is:
VGAMODE [columns], [rows]
Valid values for columns are 80 and 132; for rows, use 25, 43 or
50.
For example, if you want your screen to display 132 columns
with 25 rows, type the following and press Enter:
VGAMODE 132, 25
To use VGAMODE, you must configure the application
program that uses VGAMODE for the same screen size. Each
program has a section in this appendix explaining how to
configure it.
