The UNIX tip Command

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.

Setup

Create the file ~/.tiprc containing:
```
	force=\377
	raisechar=\377
```
Invoke tip and specify the I/O port.
```
	% tip -9600 device
```
where device is the I/O port that you wish to use in order to communicate with the Target.
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.

Vendor Port names

Sun Microsystems ttya..ttyb..etc

Silicon Graphics ttyd1..ttyd2..etc

Vendor	Port names
Sun Microsystems	ttya..ttyb..etc
Silicon Graphics	ttyd1..ttyd2..etc

Sending Files

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:

	~> filename

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

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'.
