INT 2F - ANSIPLUS.SYS v2.00+ - INSTALLATION CHECK
AX = 1A00h
BX = 414Eh ('AN')
CX = 5349h ('SI')
DX = 2B2Bh ('++')
Return: AL = FFh if installed
CF clear
ES:BX -> INT 29 entry point
CX = ANSIPLUS BCD version number (v3.10+, CH=major, CL=minor)
DL = capabilities (v4.00+)
00h full capability driver
01h reduced capability driver
2Bh full capability driver (before v4.00)
Program: ANSIPLUS.SYS is a CON device driver by Kristofer Sweger which
replaces the normal ANSI.SYS with a more powerful version having
many additional features
Notes: ANSIPLUS also identifies itself as ANSI.SYS if BX,CX, or DX differ
from the magic values above
an additional installation check is to test for the signature
"ANSIPLUS" 12 bytes before the INT 29 entry point; the version
number is also available as a four-character ASCII string (e.g.
"4.00") four bytes before the entry point
