Re: Cause IRQ5 programmatically


"gerotica" asked:

How can I trigger a IRQ5 transparently to the ISR? (ms-dos)

IRQ05 was(maybe still perhaps) the LPT (FIFO/buffer empty) IRQ.
Hook it, and check for the cause for IRQ5.
or add a softint into your IRQ5 handler.
Like the standard DOS-timer always invoke an INT0ch within the Timer-IRQ
to give any application the chance to do something on 'next Time-event'.
