tio - A simple TTY terminal I/O application

Minicom is painful to use. I found a much easier tool to use called tio - A simple TTY terminal I/O application.

Usage

---

tio /dev/ttyUSB0
tio -b 115200 /dev/ttyUSB0  # 115200 is the default baud rate

Installing Tio

---

Using the release tar method:

mkdir ~/.src
cd ~/.src
wget https://github.com/tio/tio/releases/download/v1.20/tio-1.20.tar.xz
tar -avxf tio-1.20.tar.xz
cd tio-1.20/
./configure
make && make install

Using the source source method:

sudo apt-get install autoconf
mkdir ~/.src
cd ~/.src
git clone https://github.com/tio/tio.git
cd tio
sh autogen.sh
./configure
make && make install
