Data link design pattern

I have three types of devices (USB, COM and wireless) and one PC software to connect with them. Every device have functions like connect, read and write data from RS485 network. On PC software I must implement classes application layer classes to work with devices. I am looking for some design pattern to write connection between application layer and transport layer. The first idea is to write abstract class DataLink and every device will inherit from the abstract class interface. I am looking for a better way to do this. I am using c++ v11.
