If ((_serial. The one hitch with UNIX is that device files are usually not accessable by normal. Print("SerialPortCheck " + _serial.port ) Since a serial port is a file, the open(2) function is used to access it. COM-port, or RS232) is slowly disappearing from desktop and laptop computers, but it's still a very important tool for embedded engineers and people controlling equipment in general.

When receiving data from Serial in Python, it is necessary to specify SerialPort, but if there is only one Serial and the baud rate is also known from serial.tools import list_ports These are all words that get thrown around a lot when working with. The code extract below shows how to import the serial module and configure the UART port to use COM3 at 115200 baud with no parity, one stop bit, and a timeout of two seconds.
