These procedures are not part of the language-defined libraries,
but there is an Ada binding to POSIX closely conforming to that
specified in  IEEE STD  1003.5: 1990  and
IEEE STD  1003.5b: 1996.

Source code for this binding is available at:
ftp://ftp.cs.nyu.edu/pub/gnat/3.13p/florist-3.13p.tgz or
ftp://ftp.cs.nyu.edu/pub/gnat/private/old/florist/florist-3.12p-src.tar.gz

The procedures you want are in the package POSIX.Terminal_Functions.

To use these functions you will need to open the serial port with
a procedure from the package POSIX.IO, using the name of the
serial port (/dev/ttyXX ??) -- I don't know the AIX names for serial ports.

The POSIX.IO package has facilities for controlling the blocking
behavior, and other characteristics of the port.
