Buffit v3.0 - (NOT A VECTOR!) - INSTALLATION CHECK

Program: Buffit is a shareware scrollback utility by D.T. Hamilton

Range:
INT 60 to INT 6F, selected by searching for first free vector

Notes: The Buffit installation check consists of testing whether the interrupt vector points at the ASCII signature "Buffit ". There is a private entry point (see #03267) immediately following the signature string, i.e. eight bytes beyond the address pointed at by the interrupt vector

(Table 03267) Call Buffit private entry point with:. AH = function 00h get information and hotkey state 01h get information and toggle hotkey state

Return:
AH = new hotkey state (00h enabled, 01h disabled) AL = hotkey scan code (see #00006) BH = hotkey shift states BL = ??? (01h) CX = segment of resident code DH = interrupt number used for signature pointer DL = ??? (00h) SI = INT 09 handler offset DI = INT 21 handler offset
