Understanding the serial port pin configuration is essential for anyone working with legacy hardware, industrial systems, or embedded devices. 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.

TXD, or Transmit Data, carries information from the Data Terminal Equipment (DTE) to the Data Communication Equipment (DCE). Grounding and Protection Every signal requires a return path, and the SG, or Signal Ground, pin provides this essential reference voltage point.
Conversely, RXD, or Receive Data, handles the incoming stream. This variation necessitates a clear understanding of the specific wiring standard being used to ensure proper communication and avoid damaging equipment.

Physical Connectors and Standards The most common physical shells for this interface are the DB-9 and DB-25 connectors, named for their number of pins. Key Signal Definitions At the core of the configuration are the data transmission pins.
