Basic software for PC/DOS

Basic software for PC/DOS

[Andr� LAURENS]

Starting with GNAT, I try as an exercise to port, with minimum changes, a
real-time Ada 83 PC/DOS application dealing with interrupt-driven telemetry
acquisition.

My problems are :

Where to find (or where to find information about) predefined or already
written basic Ada packages providing various low level interface with the
hardware such as i/o on PC ports, setting or clearing interrupts
(individually or globally), getting the interrupt flag vector, etc.

The only thing I could do is scanning with grep the source files of the
predefined packages...

Something that I would not like to have to do : interfacing IN, OUT, STI,
CLI assembly instructions...

Thanks for answers

If you have the version of GNAT for DOS known as EZ2LOAD, you have, or
can obtain from the same place, something called vgapck??.zip that
contains a package that does what you want.

Or check my homepage (www.pi.net/~dijklibo) for a lot of low-level DOS
examples.

Mail me if you need more help.
