xt -- A Simple Terminal Emulator

One of the most basic needs when working in the embedded control industry is to comunicate with target processors.

After migrating to Linux from MS-DOS, we searched in vain for a simple, light-weight terminal emulator program. Such a program is necessary to talk to target processors through the RS-232 ports commonly available in PC hosts. We developed xt to satisfy this need; it was initially derived from miniterm.c written by Sven Goldt.

Features

xt's main features are:

small size and simple design
portable to most Unix systems
supports up to 115200 bps
can be used with other Unix tools like expect and tee.

Note that xt performs special processing on some input characters before sending them to the serial port:

DEL is mapped to BACKSPACE
NEWLINE is mapped to CARRIAGE RETURN
xt exits upon receiving ESC or EOF
xt sends a line break upon receiving ^B

Source

You can find the source, makefile and man page here

How to install `xt`

Download the tarfile: xt.tgz from our ftp site. Untar this file with:
```
tar xzf xt.tgz
```
Get a root shell and enter into the xt directory
Type
```
make install
```
The makefile will build the program, then install executable in /usr/local/bin and the man page in/usr/local/man/man1.
