Communications  > USB Serial Adapters  

The Interworld Electronics range of USB serial adapters was created around the idea that taking advantage of new technology should not necessitate abandoning legacy devices and the applications written for them. With our USB product line we give you the freedom to implement the system you want with the resources you have and the code you have created.
