# 13 More serial tips

Contents of this section

Here are some serial tips you might find helpful...

## 13.1 `kermit` and zmodem

To use zmodem with `kermit`, add the following to your `.kermrc`:

> `

>     define rz !rz < /dev/cua3 > /dev/cua3
>     define sz !sz \%0 > /dev/cua3 < /dev/cua3

> `

Be sure to put in the device your modem is on. Then, to use it, just type `rz` or `sz <filename>` at the `kermit` prompt.

## 13.2 Setting terminal types automagically

To set your terminal type automagically when you log in, look at `/etc/ttytype`. Put in the device, and corresponding terminal type, and your `TERM` variable will be set when you log in.

Say I have a vt100 terminal on `ttyS1`, I would put:

> `

>     vt100 ttyS1

> `

in `/etc/ttytype`.

You can also get `tset` from `sunsite.unc.edu:/pub/Linux/system/Terminal-management/`. See the docs that come with `tset` to learn how to use it. `tset` can establish terminal characteristics when you log in, and doesn't depend on any defaults.

## 13.3 Color `ls` on serial connections

If `ls` is screwing up your terminal emulation with the color feature, turn it off. `ls -o`, `ls --color`, and `ls --colour` all use the color feature. Some installations have `ls` set to use color by default.

## 13.4 Printing to a printer connected to a terminal

There is a program called `vtprint` that will do this. It is available from `ftp.sdsu.edu:/pub/vtprint`. The following is from the `README` file that comes with the program:

> vtprint is a program that allows users to print from a remote UNIX host to a printer attached to their local terminal or emulator, which makes it great for printing files at home, etc. (It only does text files, though.)
