ISANSI by Dan Gookin
Copyright (C) 1990 TAB Books
ISANSI is an assembly language program that attempts to determine
if an ANSI driver is in memory. It only attempts because there are
conditions in which the program will yield a false positive. But in
99 percent of the cases, ISANSI will accurately determine whether
or not an ANSI driver is controlling the screen.
Format: ISANSI
ISANSI returns an ERRORLEVEL value of 1 if an ANSI screen driver is
present, zero if it isn't. If ISANSI returns 1, you can have your
batch file branch to special routines that take advantage of the
ANSI driver. If no ANSI driver is present, an ERRORLEVEL of zero is
returned.
