-/* agetty.c - another getty program for Linux. By W. Z. Venema 1989
-   Ported to Linux by Peter Orbaek <poe@daimi.aau.dk>
-   This program is freely distributable. The entire man-page used to
-   be here. Now read the real man-page agetty.8 instead.
-
-   -f option added by Eric Rasmussen <ear@usfirst.org> - 12/28/95
-   
-   1999-02-22 Arkadiusz Mi¶kiewicz <misiek@misiek.eu.org>
-   - added Native Language Support
-
-   1999-05-05 Thorsten Kranzkowski <dl8bcu@gmx.net>
-   - enable hardware flow control before displaying /etc/issue
