Re: Bare metal text I/O in Ada

[Fredrik <nospam@bar.com>]

Depending on which version of Rational Apex your using, you can 
implement an alternative communication method for text_io.
I think this is possible from Apex 4.0 and later.
There is a subsystem - lower_predefined.ss- which implements the 
"transportation" of your I/O. Check the 
apex_predefined_io_implementation.os_dependent_io package in there for 
details.
