Int 31/AX=0901h

DPMI 0.9+ - GET AND ENABLE VIRTUAL INTERRUPT STATE

AX = 0901h

Return:
CF clear
virtual interrupts enabled
AL = previous interrupt state (00h disabled, 01h enabled)
AH preserved

Notes: The previous state may be restored simply by executing another INT 31. A STI instruction may be used if the previous state is unimportant, but should be assumed to be very slow due to trapping by the host
