Does Raspberry Pi have RS-232?
The RS232 port can be used for remote terminal connections on the Raspberry Pi allowing remote access and control without the need for an ethernet connection. In order to connect the Serial Pi to a desktop computer you will need to use a Null-Modem cable.
What is the RS-232 port for?
(Serail port) RS-232 is the name of an interface for the interchange of serial binary data between two devices. Serial means that the data bits are send one by one after the other. RS-232 was commonly used in computers to connect devices like a printer or a telephone modem.
Is RS-232 and UART same?
No, UART and RS-232 are not the same. UART is responsible for sending and receiving a sequence of bits. At the output of a UART these bits are usually represented by logic level voltages. These bits can become RS-232, RS-422, RS-485, or perhaps some proprietary spec.

How do I open Minicom?
- The -s option use to setup minicom. Type the following command at shell prompt:
- You need to configure serial port. Use up and down arrows to select menus.
- To activate help menu press [CTRL+A] followed by [Z] for help on special keys:
- You need to connect your serial device such as router or modem using modem cable.
Does Raspberry Pi have a serial port?
Connections and signal levels The Raspberry Pi serial port consists of two signals (a ‘transmit’ signal, TxD and a ‘receive’ signal RxD) made available on the GPIO header. To connect to another serial device, you connect the ‘transmit’ of one to the ‘receive’ of the other, and vice versa.
Can Raspberry Pi read serial?
Using serial communication with your Raspberry Pi is a simple and efficient way to read and write from and to an external device. To do this, we use the GPIO pins provided on the board, and by the end of this article, you should be able to connect your Raspberry Pi to any serial device.
