I've noticed various terminal emulators that need to obtain a sane
default termios structure use very complex `hacks'. Even though POSIX
doesn't provide any functionality for this, extend our termios API with
cfmakesane(3), which is similar to the commonly supported cfmakeraw(3),
except that it fills the termios structure with sane defaults.
Change all code in our base system to use this function, instead of
depending on <sys/ttydefaults.h> to provide TTYDEF_*.
as the source of defaults for terminal device parameters.
- Do duplucate code reduction and simplification enabled by
the above.

information could only be gleaned from the the tty descriptor itself
was neglected, so never did the tty's default settings get copied from
the kernel. Specifically, this caused all manner of ctrl-keys to not
work. Fix this by calling dogettytab() in all the proper places, and
retrieving the terminfo temporarily in dogettytab().
- Initialize "rval", which would be used uninitialized
if al or pl options were set.
- Don't pass an empty string to login(1) as a user name
(this could be triggered by entering a name and then killing it
with backspace or ^U.)
- Don't loop endlessly if the al option specifies a bogus (i.e.,
not alphanumeric) auto-login name.
- Don't pass a bogus user name to login(1) if a good name were
entered and then killed with ^U.
- Exit with status 0, not 1, on receiving an EOF character,
since it's not a error condition.

in question is PPP-only line, i.e. no PPP-sequence detection is necessary and
PPP login program referenced by `pp' should be started automatically instead of
login(1)

friends are terminated and allow for a maximum
host name length of MAXHOSTNAMELEN - 1.
Put parenthesis around sizeof args.
Make some variables static.

damn useful thing for using with serial consoles in clusters etc or secure
console locations. Using a custom gettytab entry for console with
an entry like 'al=root' means that there is *always* a root login ready on
the console. This should replace hacks like those which go with conserver
etc. (This is a loaded gun, watch out for those feet!)

'sane' standard (not raw) settings before abort/exiting; move
responsibility of setting raw mode for chat-handling out of
chat.c to avoid doing redundant tc{s,g}etattr()s; move DE
pause prior setting standard mode before issue/login prompt to
avoid echoing modem connect strings. Fixed up comment styles
in a couple of places.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
emitting the initial prompt.
This is useful in a number of circumstances :
- you have (a) stupid modem(s) that assert(s) DCD too soon.
- you have dialin users with stupid diallers and poorly
written chatscripts. (esp. some Winsock diallers)
BSD/OS also has this capability.

COMPAT_43 cruft. This is supposedly the last core utility that has
been using it! (So now, one should be able to remove this option from
the config files. Be aware that the last officially released xterm
however still requires it.)
The getty has been running now for several weeks on my modem line, so
i feel safe about it.

I get on this topic will go straight to /dev/null. This is absolutely the
last word on this topic you'll see from me. Too much time has already been
wasted.
/usr/libexec/getty doesn't properly interpret the '%d' escape. It tries
to use %P to get AM or PM, but instead all it gets is "P".
