libcompat_minix-centric cleanup

remove some old minix-userland-specific stuff

	. /etc/ttytab as a file, and minix-compat function (fftyslot()),
	  replaced by /etc/ttys and new libc functions
	. also remove minix-specific nlist(), cuserid(), fttyslot(), v8 regex
	  functions and <compat/regex.h>
	. and remaining minix-only utilities that use them
	. also unused <compat/pwd.h> and <compat/syslog.h> and
	  redundant <sys/sigcontext.h>

.TH CALENDAR 1
.SH NAME
calendar \- reminder service
.SH SYNOPSIS
\fBcalendar [\fB\-\fR] [\fB\-r\fR]\fR
.br
.de FL
.TP
\\fB\\$1\\fR
\\$2
..
.de EX
.TP 20
\\fB\\$1\\fR
# \\$2
..
.SH OPTIONS
.FL "\-" "Work for every user and send mail to him"
.FL "\-r" "Restrict multiple execution on the same day"
.SH EXAMPLES
.EX "calendar" "Check \fIcalendar\fR file in current directory"
.EX "calendar" "Normary used under the control of cron(8)"
.EX "calendar \-r" " Normary used in /etc/rc file"
.SH DESCRIPTION
.PP
Basically \fIcalendar\fR program consults the file \fIcalendar\fR in the
current directory and display lines which contain today's or tomorrow's date.
Month-day formats such
as '12/25', 'Dec. 25', 'december 25', '*/25', '12/*', '*/*' are
recognized. The asterisk
means 'all' days or 'all' months. On weekends 'tomorrow' extends through
next Monday without any consideration about holidays.
To prevent ambiguity, the formats '25 Dec.' and '25/12' are not recognized.
.PP
When an argument \fB\-\fR is present, \fIcalendar\fR works for all users
with a file \fIcalendar\fR in their login directories and sends them mail.
Normally this is done daily under the control of \fIcron\fR.
.PP
The \fB\-r\fR option does its the same job as \fB\-\fR option, but touches
the \fIcalendar\fR to prevents further access on the same day.
Normally this is done in the \fI/etc/rc\fR file on a machine which may be
booted several times in one day.
.SH "SEE ALSO"
.BR cron (8).

.EX "leave 10:00" "Issue a warning at 9:55 a.m."
.EX "leave + 30" "Issue a warning in 25 minutes"
.SH DESCRIPTION
.PP
\fILeave\fR sets an alarm clock to a specified time and issues a warning
5 minutes before, 1 minute before, and at the time to leave.
It then keeps issuing warnings every minute for 10 minutes, then quits.
If no time is provided, the program prompts for one.

.TH MODEM 1
.SH NAME
modem \- switch the modem and getty state

.br
.de FL
.TP

.SH EXAMPLES
.EX "modem \-o tty00" "Set tty00 to dialout"
.EX "modem \-i2 tty00" "Set tty00 to dialin (2 rings)"
.SH DESCRIPTION
.PP
The \fIgetty\fR program allows a terminal port to be used for both dialin and
dialout.
This little program switches the getty state, and also sends
some commands to the modem attached to the specified line.
If the \fB\-o\fR flag is presnt, \fImodem\fR will put the
getty process (if any) connected to the specified line into
SUSPEND state, which means that it
will not pay attention to that line until it is reset to RESTART state.
Also, \fImodem\fR will send some (Hayes)
commands to the attached modem to disable the auto-nanswer mode.
The \fB\-i\fR flag specifies the number of times the telephone has to
ring before the modem may answer the call (to give the operator a chance).
.SH "SEE ALSO"
.BR term (1),
.BR getty (8).

.TH RLOGIND 8 "May 24, 1986"
.UC 5
.SH NAME
rlogind, in.rlogind \- remote login server
.SH SYNOPSIS
.B "login stream tcp nowait root /usr/sbin/in.rlogind in.rlogind"
.br
.B "tcpd login /usr/sbin/in.rlogind"
.SH DESCRIPTION
.B Rlogind
is the server for the
.BR rlogin (1)
program. The server provides a remote login facility
with authentication based on privileged port numbers from trusted hosts.
.PP
.B Rlogind
listens for service requests at the port indicated in
the ``login'' service specification; see
.BR services (5).
When a service request is received the following protocol
is initiated:
.IP 1)
The server checks the client's source port.
If the port is not in the range 0-1023, the server
aborts the connection.
.IP 2)
The server checks the client's source address
and requests the corresponding host name (see
.BR gethostbyaddr (3),
.BR hosts (5)
and
.BR named (8)).
If the hostname cannot be determined,
the dot-notation representation of the host address is used.
.PP
Once the source port and address have been checked,
.B rlogind
allocates a pseudo terminal (see
.BR tty (4)),
and manipulates file descriptors so that the slave
half of the pseudo terminal becomes the
.B stdin ,
.B stdout ,
and
.B stderr
for a login process.
The login process is an instance of the
.BR login (1)
program, invoked with the
.B \-r
option. The login process then proceeds with the authentication
process as described in
.BR rshd (8),
but if automatic authentication fails, it reprompts the user
to login as one finds on a standard terminal line.
.PP
The parent of the login process manipulates the master side of
the pseduo terminal, operating as an intermediary
between the login process and the client instance of the
.B rlogin
program. In normal operation, the packet protocol described
in
.BR tty (4)
is invoked to provide ^S/^Q type facilities and propagate
interrupt signals to the remote programs. The login process
propagates the client terminal's baud rate and terminal type,
as found in the environment variable, ``TERM''; see
.BR environ (7).
The screen or window size of the terminal is requested from the client,
and window size changes from the client are propagated to the pseudo terminal.
.SH "SEE ALSO"
.BR rlogin (1).
.SH DIAGNOSTICS
All diagnostic messages are returned on the connection
associated with the
.BR stderr ,
after which any network connections are closed.
An error is indicated by a leading byte with a value of 1.
.PP
.B ``Try again.''
.br
A
.B fork
by the server failed.
.PP
.B ``/bin/sh: ...''
.br
The user's login shell could not be started.
.SH BUGS
The authentication procedure used here assumes the integrity
of each client machine and the connecting medium. This is
insecure, but is useful in an ``open'' environment.
.PP
A facility to allow all data exchanges to be encrypted should be
present.
.PP
A more extensible protocol should be used.
