Interrupt Service Routine ?

Interrupt Service Routine ?

[Guenter Grau]

Hello, 

I'm looking for some sample code containing an interrupt handler with port-I/O.
I'd like to compare a software-based counter with 7-segment-output with a
VHDL description of the same to provide a short introduction to VHDL by 
comparison to Ada. As I'm not familiar with Ada any more :( I would be grateful
for a code snippet with an ISR doing some port-output that could in principal
be compiled. It'll be part of an exercise in our lecture on "Microelectronics". 

thanks in advance

If it can help, I have made a fine timer interrupt with GNAT/DOS -
not professional at all but works on DOSes, Win95 and Win NT.
