.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
|
|
sends it the ``from''
|
|
file. If the ``to'' file isn't specified the ``from'' file name is used.
|
|
This command is actually a
|
|
.Ux
|
|
specific version of the ``~>'' command.
|
|
.It Ic \&~t Ar from Op Ar to
|
|
Take a file from a remote
|
|
.Ux
|
|
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.
|
|

|
|
their abbreviations, and their default values.
