We are not going to go into details on all the possible configurations, however you can read about it here if you are interested.

Typically RS-232 is used without hardware flow control and at full duplex. Two optional lines RTS and CTS are provided for this function. Hardware flow control can also be enabled in order to mitigate the flow of data. However, depending on the higher level protocols, there may be a need to block the transmitter while receiving. This is called full-duplex and it is the standard means for communicating over serial. The separate RX and TX lines mean that data can flow in both directions at the same time. The minimum connection required for bidirectional communication is three signals: transmit (TX), receive (RX), and ground. RS-232 is a point-to-point signalling standard, meaning only two devices can be connected to each other.
Tera term ascii serial#
The UART module may support several features which allow it to interface with various signaling standard such as RS-232 or RS-485 – another serial interface commonly used in industrial applications. RS-232 has no dependency on any higher level protocol, however it does have a simple layer 1 (physical layer) set of standards which must be followed. The UART is the peripheral on the microcontroller which can send and receive serial data asynchronously, while RS-232 is a signalling standard. It is important to distinguish the difference between the terms UART and RS-232.

In this lesson, we will learn a bit about the theory behind UART and RS-232, learn how to write a simple UART driver for the MSP430, and create a menu which gives the user the ability to change the frequency of the blinking LED during runtime. These days most PCs not longer have a serial port, so it is more commonly seen implemented using USB, however the concept is the same. The debug console is a serial interface which historically is implemented as RS-232 to connect with a PC serial port. When a board arrives in the hands of the software/firmware team, the first step is typically to get the debug console functional. One of the most common interfaces used in embedded systems is the universal asynchronous receiver/transmitter (UART). It could be to transferring data to another device, sending and receiving commands, or simply for debugging purposes. An embedded system often requires a means for communicating with the external world for a number of possible reasons.
