On Windows 10, the ability to check the computer serial number can come in handy in many scenarios. For instance, when you need to create an inventory of the devices connected to your home network. Read and write data over a serial connection. PySerial includes a small console based terminal program called serial.tools.miniterm. It can be started with python-m serial.tools.miniterm (use option -h to get a listing of all options).

Opening serial ports¶
Open port at “9600,8,N,1”, no timeout:
Open named port at “19200,8,N,1”, 1s timeout:
Open port at “38400,8,E,1”, non blocking HW handshaking:
Configuring ports later¶
Get a Serial instance and configure/open it later:
Also supported with context manager:
Readline¶
Be careful when using readline(). Do specify a timeout when opening theserial port otherwise it could block forever if no newline character isreceived. Also note that readlines() only works with a timeout.readlines() depends on having a timeout and interprets that as EOF (endof file). It raises an exception if the port is not opened correctly.
Do also have a look at the example files in the examples directory in thesource distribution or online.
Note
The eol parameter for readline() is no longer supported whenpySerial is run with newer Python versions (V2.6+) where the moduleio is available.
EOL¶
To specify the EOL character for readline() or to use universal newlinemode, it is advised to use io.TextIOWrapper:
Testing ports¶
Listing ports¶
python-mserial.tools.list_ports will print a list of available ports. Itis also possible to add a regexp as first argument and the list will onlyinclude entries that matched.
Note
Serialize
The enumeration may not work on all operating systems. It may beincomplete, list unavailable ports or may lack detailed descriptions of theports.
Accessing ports¶
pySerial includes a small console based terminal program calledserial.tools.miniterm. It can be started with python-mserial.tools.miniterm<port_name>(use option -h to get a listing of all options).
Reading and writing data over a serial connection.
The Adafruit Circuit Playground Express can read data from and write data to another computer or device with a serial connection using USB. To use serial communication between your board and MakeCode, you need the MakeCode for Adafruit app for Windows 10 and a USB cable.
You can also write data to an output log with the console functions without having to use a serial connection.
