COM Port Number: Each serial port on the PC is labeled COM1, COM2, etc. You need to figure out which one you're attached to. If there is a serial port at the back of the computer, chances are it's COM1. However, even if there is only 1 serial port visible in the back, its possible its COM2, or COM3 especially if there is a modem.

The concept of serial communication is simple. The serial port sends and receives bytes of information one bit at a time. Although this is slower than parallel communication, which allows the transmission of an entire byte at once, it is simpler and can be used over longer distances. For example, the IEEE 488 specifications for parallel ...

Serial port communication uses RS-232 standard for transferring data. Information is sent in small packets of data called data frames. A data frame consists of the following sequence: a start bit, the actual data word, an optional parity bit and ends with one or two stop bits. The data word can be 7 or 8 bits long.

The communication mode of esp32 and STONE TFT LCD adopts serial port communication. This application function is divided into three parts: temperature monitoring, humidity monitoring, and light monitoring. After startup, there will be a boot interface first. After a moment, you will enter the main function interface.
Serial Port Communication - CodeProject
It allows you to establish a connection to a serial port, connect to another communication device (a modem, for instance), issue commands, exchange data, and monitor and respond to various events and errors that may be encountered during a serial connection. Possible Uses Dial a phone number. Monitor a serial port for incoming data.
