ST Serial is a type of communication protocol that is commonly used for transmitting data between electronic devices. It is based on the RS-232 standard, which defines the electrical and mechanical characteristics of the communication interface.

ST Serial is a point-to-point protocol, meaning that it allows communication between two devices. It uses a single data line, a single clock line, and optionally one or two control lines. The protocol uses a start bit, data bits, a parity bit, and a stop bit to transmit data between the devices.

ST Serial is widely used in various applications such as computer networking, industrial automation, and telecommunications. It is a simple and reliable communication protocol, which makes it popular for many applications that require low to moderate data rates.

ST Serial has been largely replaced by newer communication protocols such as USB and Ethernet, but it still remains in use in many legacy systems and applications.
