Abstract
This specification presents a mechanism to provide automatic configuration capability to peripheral devices that connect to a PC using Asynchronous Serial Data Interchange on standard serial ports, commonly known as COM ports. This enables full Plug and Play for the PC system, including external serial peripherals, referred to here as COM Devices.
The essential elements of Plug and Play COM are:
- Detect attachment of serial devices
- Identify the device, and notify the operating system of its arrival
- Detect detachment of serial devices, and notify the operating system of its removal
