Talk:Universal asynchronous receiver-transmitter

message: The IBM PC compatibles used National Semiconductor 8250, not the Intel serial chip - because the National chips had built-in programmable baud rate generators. The sucessors were also made by National. 
This article needs a block diagram of a UART, too. --Wtshymanski 05:58, 13 Apr 2005 (UTC)

message: These standards are discussed in their own articles; the UART may interface to the control lines of an RS 232 interface but doesn't directly generate the voltage levels that go out on the wire. --Wtshymanski 17:49, 17 May 2005 (UTC)
thread_title: RS 232 and so forth

message: "INT 14" is hopelessly IBM-PC specific and not appropriate for a general article on UARTS. 
I've moved the following lines here but I don't think they belong in this article at all. --Wtshymanski 18:57, 24 February 2006 (UTC)

message: Someone gave a pronunciation of OO-wuh AT. I thought this was odd, so I edited it out. Please replace if I'm wrong - there's an English IPA key at . kwami 06:16, 16 October 2007 (UTC)

message: An asynchronous transmission sends nothing over the interconnection when the transmitting device has nothing to send; but a synchronous interface must send "pad" characters to maintain synchronism between the receiver and transmitter.
The two modes need to be swapped, don't they? Sevcsik 20:12, 27 October 2007 (UTC)

message: The term "TAE" is mentioned but this term is not defined in this article or in other articles in Wikipedia (in a relevant meaning, anyway). I would love to rectify this but I don't know what's TAE and neither Google "define" nor the free acronyms dictionary had the answer :-(

replies: text: It caught my attention too. I also couldn't find any other reference to TAE so I checked the page history and it was the last change made. I checked the  author's recent contributions and they are all acts of vandalisms. My guess is a vandal got newly  assigned that IP (some earlier contributions are a legitimite ones). I reverted the edit. If anybody can come with a good explanation what TAE is, just put it back, please. 24.80.185.126 (talk) 10:13, 10 September 2008 (UTC)

message: What is the purpose of the UART models section? I am sure there are thousands of different chips which support UART and which are not shown there. I think that section should be deleted entirely. --IngenieroLoco (talk) 11:15, 29 November 2016 (UTC)
replies: text: I think that a few famous/significant historical units should be represented, plus a couple of the chips commonly (well, "commonly" until serial ports went away) used in PCs (e.g. 8250 and 16550), at least. And some indication of the difference between those (which are addressable devices that can sit on a bus) and the old chips should be included. On the other hand, I agree that Wikipedia should not be a parts list. Jeh (talk) 11:32, 29 November 2016 (UTC)
thread_title:  UART models section 

message: I flagged "UARTs are now commonly included in microcontrollers", the article is 16 years old! It would be nice to cite a reference. The History section stops short of covering this advance. -- Skierpage (talk) 23:13, 18 April 2018 (UTC)
thread_title:  When did microcontrollers absorb the UART? 

message: Note that the 8251 is actually a USART, which can run in either asynchronous or synchronous mode. I believe some of the others listed along with it are also USART or similar. Gah4 (talk) 01:46, 13 April 2023 (UTC)
