Description

---

The Abstract Control Model (ACM) is part of the USB Communications Device Class (CDC) standard which allows modem like devices to be supported by USB with a standardized protocol for data transfer and modem control.

A CDC ACM device is defined by information in the interface descriptors and is not specific to any product and vendor ID. There are numerous devices that support the CDC ACM protocol and some of the most important from Ultibo are the Arduino Mega 2560 R3 and the Arduino Due.

This driver presents any device recognized as a CDC ACM as a generic serial interface device that can be accessed using the API in the Serial unit. It should not be necessary to directly call any of the functions in this unit from application code.
