What is a Serial Cable using IrDA Protocol?

A Serial Cable using IrDA (Infrared Data Association) Protocol refers to a communication interface that uses infrared (IR) signals to transmit data between devices, typically in a wireless or short-range setup. IrDA is a protocol that enables devices to communicate via infrared light, and it is often used for short-range data transfers between devices such as computers, mobile phones, PDAs, and printers.

In this context, the Serial Cable using IrDA might refer to a USB-to-serial IR adapter or an IR transceiver that provides infrared connectivity. Devices using this type of cable often allow a serial interface (like RS-232) to communicate over infrared instead of traditional wired connections.
