I've had the same problem trying to read single keystrokes from the keyboard.
The main difference is i'm running Janus ADA on a standalone
IBM 286/386 compatable. I also have access to the Meridian
ADA Compiler and libraries but being a relatively new user
to ADA i'm not yet sure what it can do.

At least you're not the one :-)

My second question is :-

I want to be able to put higher order ASCII values ( greater than 127 ) 
to the screen..using the same ADA and hardware as above.

Any suggestions please post here or email me. (Please excuse my ignorance :-)
