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(Binary Coded Decimal) A method of data storage where two decimal digits are stored in each byte, one in the upper four bits and the other in the lower four bits. Since only the values 0 through 9 are used in each half of a byte, BCD values can be read as decimal numbers on a hexadecimal display of memory or a file. 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 SeeAlso: AX=1AA5h,AX=1AA6h,AX=1AA7h,AX=1AA8h,AX=1AA9h,AX=1AAAh,AX=D44Fh
