You are right, the approach by a user handler attached to the relevant
UNIX signal is certainly the good approach to cope with terminal
modifications. I am looking at some documentation to understand how to
proceed with these handles in Ada (Rosetta Code ans Big Online Book of
Linux Ada to begin).

Thank you.
