Hi,
Thanks for the help on my first question (see topic IO-PORTS). I already
have a sort of working prototype but still I have some questions left.
The program has to be interrupt-driven. What interrupt_id do I have to
use for the COM1-port (I suppose Names.SIGINT ??? What else, because
it's not working).
How to use the Interrupt_Priority pragma? I mean, you have to write
something like: pragma Interrupt_Priority(???).. But I don't really know
what to write in the ??? place, even constants like Max_Priority as
specified in the Systems package don't compile..
BTW My PC is an Intel with Windows 98.
Any help is welcome,
Alexander
