TXD, or Transmit Data, carries information from the Data Terminal Equipment (DTE) to the Data Communication Equipment (DCE). When the sending device is ready, it asserts RTS, and the receiving device responds by setting CTS, signaling that it is ready to accept the next buffer of information.

A basic three-wire connection using TXD, RXD, and Ground is sufficient for simple data exchange between two devices. Grounding and Protection Every signal requires a return path, and the SG, or Signal Ground, pin provides this essential reference voltage point.
While the physical shape is standardized, the assignment of signals to specific pins can vary depending on the application. Practical Applications and Pinouts In practice, the specific wiring of a serial port pin out depends on the desired functionality.

Although USB has largely replaced this interface for consumer use, the RS-232 standard remains a robust solution for reliable, long-distance communication in industrial environments. Without these two pins, no actual data could flow between devices, making them the primary pathway for communication.
