Setserial is a command line tool in Linux used for configuring serial port settings on the system. It allows the user to view and modify various parameters of serial ports such as baud rate, data bits, parity, stop bits, and flow control. The tool is primarily used to manage communication settings for devices connected to serial ports, such as modems, printers, or serial devices. Setserial can be used to display information about the current serial port configuration, including port number, IRQ, and I/O address. It also provides a flexible interface to modify these settings, enabling users to manually set or change serial port parameters. Setserial is an essential utility for controlling and troubleshooting serial communication in Linux systems, ensuring efficient and reliable data transfer between devices.
