SerialPortEmulator

This is a serial port emulator. This is done by creating pairs of ports on /dev where writing data on one port can be read on the pair and vice-versa.

Installation

1. Install the dependencies. On your Debian-like Linux machine, run:

sudo apt install python3-serial linux-headers-`uname -r` gcc binutils make

2. Inside the driver folder, run:

make clean all
sudo make modules_install
sudo make install

3. Set read and write permissions on the pairs of devices to be used

Example: for the EmulatedPort 0 device:

sudo chmod 777 /dev/ttyEmulatedPort0
sudo chmod 777 /dev/ttyExogenous0

Uninstallation

Inside the 'driver' folder, run:

sudo make uninstall

Use

After the installation, by default, it will be instatiated on /dev many pairs of devices:

• /dev/ttyEmulatedPort0 <---> /dev/ttyExogenous0
• /dev/ttyEmulatedPort1 <---> /dev/ttyExogenous1 ...

And so on. Writing on one device will make its content to be read on the other pair, and vice-versa

You MUST at least execute a read operation on the Exogenous port to make the OS create the necessary structures

Example:

1. Open a terminal window and run:

cat /dev/ttyExogenous0

The device will be put on waiting for incoming data

2. Open another terminal window and run:

echo "XYZ" > /dev/ttyEmulatedPort0

Return to the first terminal Window. It should appear the 'XYZ' on it.
