+.Sh DESCRIPTION
+.Nm Tip
+and
+.Ar cu
+establish a full-duplex connection to another machine,
+giving the appearance of being logged in directly on the
+remote cpu.  It goes without saying that you must have a login
+on the machine (or equivalent) to which you wish to connect.
+The preferred interface is
+.Nm tip  .
+The
+.Ar cu
+interface is included for those people attached to the
+``call
+.Ux Ns ''
+command of version 7.  This manual page
+describes only
+.Nm tip  .
+.Pp
+Available Option:
+.Bl -tag -width indent
+.It Fl v
+Set verbose mode.
+.El
+.Pp
+Typed characters are normally transmitted directly to the remote
+machine (which does the echoing as well).  A tilde (`~') appearing
+as the first character of a line is an escape signal; the following
+are recognized:
+.Bl -tag -width flag
+.It Ic \&~^D No or Ic \&~ .
+Drop the connection and exit
+(you may still be logged in on the
+remote machine).
+.It Ic \&~c Op Ar name 
+Change directory to
+.Ar name
+(no argument
+implies change to your home directory).
+.It Ic \&~!
+Escape to a shell (exiting the shell will
+return you to tip).
+.It Ic \&~>
+Copy file from local to remote.
+.Nm Tip
+prompts for the name of a local file to transmit.
+.It Ic \&~<
+Copy file from remote to local.
+.Nm Tip
+prompts first for the name of the file to be sent, then for
+a command to be executed on the remote machine.
+.It Ic \&~p Ar from Op Ar to 
+Send a file to a remote
+.Ux
+host.  The put command causes the remote
+.Ux
+system to run the command string ``cat > 'to''', while
+.Nm tip

+host.
+As in the put command the ``to'' file
+defaults to the ``from'' file name if it isn't specified.
+The remote host
+executes the command string ``cat 'from';echo ^A'' to send the file to
+.Nm tip  .
+.It Ic \&~|
+Pipe the output from a remote command to a local
+.Ux
+process.
+The command string sent to the local
+.Ux
+system is processed by the shell.
+.It Ic \&~$
+Pipe the output from a local
+.Ux
+process to the remote host.
+The command string sent to the local
+.Ux
+system is processed by the shell.
+.It Ic \&~C
+Fork a child process on the local system to perform special protocols
+such as \s-1XMODEM\s+1.  The child program will be run with the following
+somewhat unusual arrangement of file descriptors:
+.nf
+.in +1i
+0 <-> local tty in
+1 <-> local tty out
+2 <-> local tty out
+3 <-> remote tty in
+4 <-> remote tty out
+.in -1i
+.fi
+.It Ic \&~#
+Send a
+.Dv BREAK
+to the remote system.
+For systems which don't support the
+necessary
+.Ar ioctl
+call the break is simulated by a sequence of line speed changes
+and
+.Dv DEL
+characters.
+.It Ic \&~s
+Set a variable (see the discussion below).
+.It Ic \&~^Z
+Stop
+.Nm tip
+(only available with job control).
+.It Ic \&~^Y
+Stop only the ``local side'' of
+.Nm tip
+(only available with job control);
+the ``remote side'' of
+.Nm tip  ,
+the side that displays output from the remote host, is left running.
+.It Ic \&~?
+Get a summary of the tilde escapes
+.El
+.Pp
+.Nm Tip
+uses the file
+.Pa /etc/remote
+to find how to reach a particular
+system and to find out how it should operate while talking
+to the system;
+refer to
+.Xr remote  5
+for a full description.
+Each system has a default baud rate with which to
+establish a connection.  If this value is not suitable, the baud rate
+to be used may be specified on the command line, e.g.
+.Ql "tip -300 mds" .
+.Pp
+When
+.Nm tip
+establishes a connection it sends out a
+connection message to the remote system; the default value, if any,
+is defined in
+.Pa /etc/remote
+(see
+.Xr remote 5 ) .
+.Pp
+When
+.Nm tip
+prompts for an argument (e.g. during setup of
+a file transfer) the line typed may be edited with the standard
+erase and kill characters.  A null line in response to a prompt,
+or an interrupt, will abort the dialogue and return you to the
+remote machine.
+.Pp
+.Nm Tip
+guards against multiple users connecting to a remote system
+by opening modems and terminal lines with exclusive access,
+and by honoring the locking protocol used by
+.Xr uucico 8 .
+.Pp
+During file transfers
+.Nm tip
+provides a running count of the number of lines transferred.
+When using the ~> and ~< commands, the ``eofread'' and ``eofwrite''
+variables are used to recognize end-of-file when reading, and
+specify end-of-file when writing (see below).  File transfers
+normally depend on tandem mode for flow control.  If the remote
+system does not support tandem mode, ``echocheck'' may be set
+to indicate
+.Nm tip
+should synchronize with the remote system on the echo of each
+transmitted character.
+.Pp
+When
+.Nm tip
+must dial a phone number to connect to a system it will print
+various messages indicating its actions.
+.Nm Tip
+supports the
+.Tn DEC DN Ns-11
+and
+Racal-Vadic 831 auto-call-units;
+the
+.Tn DEC DF Ns \&02
+and
+.Tn DF Ns \&03 ,
+Ventel 212+, Racal-Vadic 3451, and
+Bizcomp 1031 and 1032 integral call unit/modems.
+.Ss VARIABLES
+.Nm Tip
+maintains a set of
+.Ar variables
+which control its operation.
+Some of these variables are read-only to normal users (root is allowed
+to change anything of interest).  Variables may be displayed
+and set through the ``s'' escape.  The syntax for variables is patterned
+after
+.Xr vi  1
+and
+.Xr Mail  1  .
+Supplying ``all''
+as an argument to the set command displays all variables readable by
+the user.  Alternatively, the user may request display of a particular
+variable by attaching a `?' to the end.  For example ``escape?''
+displays the current escape character.
+.Pp
+Variables are numeric, string, character, or boolean values.  Boolean
+variables are set merely by specifying their name; they may be reset
+by prepending a `!' to the name.  Other variable types are set by
+concatenating an `=' and the value.  The entire assignment must not
+have any blanks in it.  A single set command may be used to interrogate
+as well as set a number of variables.
+Variables may be initialized at run time by placing set commands
+(without the ``~s'' prefix in a file
+.Pa .tiprc
+in one's home directory).  The
+.Fl v
+option causes
+.Nm tip
+to display the sets as they are made.
+Certain common variables have abbreviations.
+The following is a list of common variables,
+their abbreviations, and their default values.
+.Bl -tag -width Ar
+.It Ar beautify
+(bool) Discard unprintable characters when a session is being scripted;
+abbreviated
+.Ar be  .
+.It Ar baudrate
+(num) The baud rate at which the connection was established;
+abbreviated
+.Ar ba  .
+.It Ar dialtimeout
+(num) When dialing a phone number, the time (in seconds)
+to wait for a connection to be established; abbreviated
+.Ar dial  .
+.It Ar echocheck
+(bool) Synchronize with the remote host during file transfer by
+waiting for the echo of the last character transmitted; default is
+.Ar off  .
+.It Ar eofread
+(str) The set of characters which signify an end-of-transmission
+during a ~< file transfer command; abbreviated
+.Ar eofr  .
+.It Ar eofwrite
+(str) The string sent to indicate end-of-transmission during
+a ~> file transfer command; abbreviated
+.Ar eofw  .
+.It Ar eol
+(str) The set of characters which indicate an end-of-line.

+.Ar es  ;
+default value is `~'.
+.It Ar exceptions
+(str) The set of characters which should not be discarded

+.It Ar prompt
+(char) The character which indicates an end-of-line on the remote

+command is based on receipt of this character.
+.It Ar raise
+(bool) Upper case mapping mode; abbreviated

+default value is
+.Ar off  .
+When this mode is enabled, all lower case letters will be mapped to
+upper case by
+.Nm tip

+.Ar beautify
+switch is on, only printable
+.Tn ASCII
+characters will be included in
