The pty.openpty() function returns two file descriptors, one for the master and one for the slave. Python has a pty module that you can use to setup this master and slave pair. The master is usually devptmx on linux, while the slave is often of the form devpts where x is any integer. One end is the master, which in my case is where my dummy serial device is listening. Pseudoterminals can be used (and are used) for many things, but serial communication can be one.īasically it is just a file that software can write to or read from as if it was a serial connection.
