Printer Interrupt

Post by Liam » Wed Jun 18, 2003 12:55 pm


I want to use the interrupt line on the EPP to trigger the printer IRQ7
which I can then use in my program to stop a timer.

What do I have to do as regards setting up the port. devc-par doesn't run a
start up.
When I read the level of the interrupt line it seems to float high, how can
this be used to trigger an interrupt if it floats high?.

Do I have to do something for this interrupt to be receognised, IE tie lines
set control registers etc? I have selected EPP in the BIOS.
