Talk:Hayes AT command set

message: >originally developed for the Hayes Smartmodem 2400.
Surely this is not the case, my Hayes Smartmodem 300 used AT commands?
I recall AT for Hayes prior to mid 70's....you may recall the S100 bus hobby computers....and the many products, accessories available14.140.155.100 (talk) 13:14, 7 September 2014 (UTC)

message: It's not a really well-known fact, but on many modems, register S2 controls which character is the escape character.  The default is 43, +.  However, 255 is a special case.  ATS2=255 disables the escape system entirely.  This eliminates the problem of embedded +++ sequences.  To hang up while in this mode, you drop the DTR signal on the serial port.  There is no way to enter command mode while connected with escapes disabled, but most applications of modems have no use for this other than hanging up. -- Myria 06:47, 3 March 2006 (UTC)

message: The main article could be improved if someone included a list of which modems observed the Hayes command set, and the years they were introduced. —The preceding unsigned comment was added by 198.177.27.23 (talk) 05:55, 30 April 2007 (UTC)
replies: text: Just about ALL dial-up modems in existence do.  That would be a very, very long list of modems.  If anything, a list of modems that do NOT support the Hayes command set would be more meaningful - and all such modems are ancient dinosaurs from the 70's and early 80's, probably no faster than 300 or 1200 baud.

thread_title:  List of modems having a Hayes command set 

message: Various other sites on the web claim that S8 register default is 2 making the comma in dial commands a _two_ second pause (text says 1, table says 2)? I do not have a real hayes modem to check this. Kjw 10:10, 30 August 2007 (UTC)
thread_title:  default pause for comma 

message: I propose a Wikipedia page for all AT commands, as I need to maintain this resource for my own needs and believe this would also be useful for others.
I shall wait for a week for your response to this idea, before starting: "List of AT commands", "List of modem commands" or similar.
I propose a table with the following columns : Command, Meaning, Reference.

replies: text: How "full" of a list did you have in mind?  If you consider the numerous commands that apply to fax, voice, and cellular telephony, not to mention all the syntax variations of identical commands across different chipsets and modem manufacturers, then you're up to several hundred unique AT commands and S-registers.  At that point, what you're contemplating is exhaustively large reproduction of what is essentially the content of the manual.  Why not just download the manual for the chipset of your choice?

replies: text:  I don't think this is a good idea. This varies from model to model and by manufacturer - you should at least add a column explaining which modems the command works. You would need published references to back up the list - otherwise there will be no way to detect vandalism. --Wtshymanski (talk) 15:30, 22 November 2009 (UTC)
replies: text:  Even with published references it could be a magnet for vandalism. There were a couple of accounts over the summer who delighted in tweaking city climate tables: just changing a temperature by a degree or rainfall by a few mm. Those tables were referenced, but comparing them with the published sources to detect vandalism was time-consuming and I'm sure some were missed. Anyway, Wikipedia is not a manual. - Pointillist (talk) 16:10, 23 November 2009 (UTC)

message: The reference pointing to "developer.sonyericsson.com" now get us to a "We've moved" page. I do not know what that page contained but i found an AT commands document on their site, that might be useful as a reference.

message: Did any of the Hayes compatible modems have DIP switches for things like frame references, voltage locks, or that sort of thing?   I'm not a hardware guy, but I seem to remember running into some pretty strange modems in 1985.   Like a modem that was 'supposed' to be compatible with the Hayes command set, but only if an internal DIP switch was set appropriately.    The main page of this article could be improved by explaining what other command sets were the chief competitors to the Hayes compatible modems, then add a Wiki link so we could compare.    216.99.201.158 (talk) 05:11, 22 October 2011 (UTC)
thread_title:  DIP switches to control Hayes command set? 

message: The "too technical" tag should be removed.  Yes, there's technical information -- that's
probably what most readers came for -- but the first section (History) is an excellent
summary of the subject.  I've always believed that the best way to teach science/technology
is through its history -- what the problem is, how it was explored, and how it was solved.
So rather than "too technical", I would say that this article is excellent both as an
introduction and as a reference.

message: Shouldn't this page be renamed "AT command set" instead of "Hayes command set", so as to not be attached to one company name, even if they are the originator of the command set? Currently working in the radio world, I hear them a lot more described as AT commands than Hayes commands...  — Preceding unsigned comment added by Xibe (talk • contribs) 14:01, 9 October 2019 (UTC)
