*initial-terminal-io*

When Lisp starts up, this symbol is bound to a bidirectional stream with input and output corresponding to the normal Unix streams stdin and stdout or their equivalents on Windows. This symbol is never bound to any other value by Allegro CL and is thus available for application programs which need to guarantee access to the original stdin and stdout.

Users are strongly discouraged from changing the value of this symbol.
