<!--INDEX "tip command" -->
<!--INDEX UNIX tip /etc/remote linesync -->

The UNIX tip command is a very simple terminal emulator. It does not
support scripting or specific terminal emulation, but it does provide
a mechanism to communicate with a target via an RS-232 link, and
permit files to be downloaded.<p>

</dl><h2>Setup</h2><dl><dd>

<ul>
<li>Create the file ~/.tiprc containing:
<pre>
	force=\377
	raisechar=\377
</pre>
<li>Invoke tip and specify the I/O port.
<pre>
	% tip -9600 <i>device</i>
</pre>

where <i>device</i> is the I/O port that you wish to use in order to
communicate with the Target.<p>

Unfortunately there isn't much standardization of device
names across different UNIX vendors, so you will probably have to ask
around a little in order to find out the names of the serial ports on
your system. Here are some values that I am aware of.<p>

<center>
<table border cellpadding=6 width=80%>
<tr><th>Vendor</th><th>Port names</th></tr>
<tr><td>Sun Microsystems</td><td>ttya..ttyb..etc</td></tr>
<tr><td>Silicon Graphics</td><td>ttyd1..ttyd2..etc</td></tr>
</table>
</center><p>
</ul>

</dl><h2>Sending Files</h2><dl><dd>

Normally everything you type is sent directly to the target. However,
if you start a line with '~' it is interpreted as a direct command for tip.
For example, to download a file you type:<p>

<pre>
	~> filename
</pre>

That is, tilde, followed by '>' followed by the name of the file
that you wish to download.<p>

To obtain a complete list of the commands available type '~?'. 
tip also maintains a large number of variables that
control its operation. You may display the state of these variables
by typing '~s all'.<p>
