Minix getty

===========

Very simple C implementation of a UNIX getty, originally from Minix.

Initialize and serve a login-terminal for INIT.  Also, select the

correct speed.

**Usage:**

    getty [-h] [speed]

It is expected that the [init](https://github.com/troglobit/finit) that

spawns getty has first opened up the TTY and set up STDIN, OUT and ERR.

Origin & References

-------------------

The original version of this getty stems back to the early 1990's.  It

was written by Fred van Kempen.  It later found its way to Minix, which

adopted version 3.4, 02/17/90, and started stripping it down to much of

what is its current form.  The software was open sourced along with the

rest of Minix under the 3-clause BSD license in April, 2000.

This version has been extended and in critical parts rewritten to suit

any UNIX system.

ChangeLog

---------

* All the good stuff removed to get a minimal getty, because many modems

  don't like all that fancy speed detection stuff.

  03/03/91 Kees J. Bot 

* Uname(), termios.  More nonsense removed.  (The result has only 10% of

  the original functionality, but a 10x chance of working.)

  12/12/92 Kees J. Bot 

* Customizable login banner.

  11/13/95 Kees J. Bot 

* Suspend/resume signals removed.

  2001-04-04 Kees J. Bot 

* Removed unused custom banner and returned speed option functionality

  (by simply calling stty).

  2012-09-24 T. Veerman

* Refactored banner code to read std `/etc/issue` instead.  Refactored

  speed handling to use direct termios instead of stty.

  2016-07-27 J. Nilsson 

* Add support for Ctrl-U on `login:` prompt, fix build warnings, use

  std `err.h` functions for error handling.  And more.
