Python Serial Without Pyserial

I have been having problems with Pyserial (this is not the first: PySerial write errors (baudrate sensitive)) The accepted answer for this question: pySerial works fine in Python

Solution 1:

Looking around I found this example.

From the site:

arduinoserial.py is a Python port of Tod E. Kurt's arduino-serial.c program for communicating with an Arduino microcontroller board over a serial port. It only uses standard Python modules (notably termios and fcntl) and does not require any special serial communications modules.

Like Tod's program, you can use it from the command line.
