This class API is compatible to Serial with a few exceptions: write_timeout is not implemented; The current implementation starts a thread that keeps reading from the (internal) socket. The thread is managed automatically by the rfc2217.Serial port object on open() / close(). However it may be a problem for user applications that like to use select instead of threads.

Serial communication is the process of sending one bit of data at a time sequentially from one place to another, like say sending data from your Raspberry Pi to a connected Arduino or vice versa. USB is one of the most common methods used for serial communication. Hence, the name Universal Serial Bus.

Jun 5, 2017 · Open serial port.
