title: UART controller or RS232 controller? Is UART a general word?
body: <p>I have a question regarding UART controller.</p>
  
  <p>Is UART controller a general name?</p>
  
  <p>i mean that if we use RS-232 protocol, we should name this UART controller, RS-232 controller and if we use RS-485 as protocol, we should call this UART controller, a RS-485 controller and so on?</p>
  
  <p>I've noticed that we <strong>generally</strong> say network controller (protocols:Ethernet, token ring,ATM,..) and if the protocol implemented is Ethernet for example, we say Ethernet controller. Is it a correct comparison between UART controller and Network controller meaing that they both are general names? </p>
  
  <p>Thanks a lot for your clarifications</p>
