UART controller or RS232 controller? UART a general word?

[dummygirl]

Hi guys,

i have a question regarding UART controller. Is UART controller a general name? 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.

i noticed that we say network controller (Ethernet, token ring,ATM,..) generally and if the protocol implemented in the network controller is Ethernet, we use the word Ethernet controller. Is it a correct comparison?

Go here for a definition (and additional background on a UART (Universal Asynchronous Receiver/Transmitter):

Yes, a UART is synonymous with the term "serial port controller".

Please clarify your question regarding network controller vs. ethernet controller, but I think the answer is "yes". You can use the terms as you seem to indicate. However, the terms for this more often used is NIC (network interface controller) or simply network adapter.
