问题描述
在与同事讨论如何处理AT命令的同时，我们发现与我们的信念背道而驰在V.250中未指定AT&W(存储用户配置文件)(仅指定相关的ATZ和AT&F)，让我们想知道-那么它在哪里指定?
While discussing how to process AT commands with a colleague,we discovered that contrary to our belief the commandAT&W (store user profile) is not specified in V.250(it only specifies ATZ and AT&F, which are related),leaving us wondering - where is it specified then?
更新:是的，我们希望该命令的起源于Hayes命令集，几乎所有基本语法命令都可以.但是，大部分的Hayes命令已导入到正式的诸如 V.250 之类的标准，或者3GPP的 27.007 .由于V.250没有导入此命令，我们想知道可能是因为它是在其他一些标准中指定的.
Update: Yes, we expected the command to have its origin in theHayes command set, virtually all the basic syntax commands does.However, most of the Hayes command have been imported into formalstandards like V.250 by ITU or 27.007 by 3GPP.Since V.250 did not import this command we were wonderingthat it might be because it was specified in some other standard.
在任何情况下，其他标准都定义了各种命令.这是我在源代码中添加的注释的摘录去年我使用AT+VTS命令时(顺便说一下，这是最不规范的我见过的参数语法！).
And in any case other standards have defined various commands.Here is an extract from a comment I put in the source codewhen I were working with the AT+VTS command last year(which has by the way the most non-standardparameter syntax I have ever seen!).
有人参考正式的标准/文档吗?(如上)定义了AT&W?我们不仅在寻找某些随机调制解调器的制造商文档(除非是原始的Hayes调制解调器).
Does anyone have a reference to a formal standard/documentation(like above) that defines AT&W ? We are not just looking formanufacturer documentation of some random modem (unless for the original Hayes modems).
推荐答案
经过一些搜索，我认为我已经找到了所要查找的答案，但是，如果您碰巧引用了包含AT&W.
After some searching I think I have found answers to what I was looking for, however please add additional answers if you happen to have a reference to a standard containing AT&W.
虽然我没有找到有关Smartmodem 1200或Smartmodem 2400调制解调器的任何手册，我发现了一篇名为 Hayes调制解调器用户技术参考的论文.关于AT&W的内容如下:
While I have not found any manual for the Smartmodem 1200 or Smartmodem 2400 modems,I found a paper called Technical Reference for Hayes Modem Userswhich says the following about AT&W:
&W - Write Active Profile to Memory
The &W command stores certain command options and S-register values into
one of the modem's two nonvolatile stored profile memory locations. The
command options and register values stored depend on the particular
modem. These are indicated in the user documentation for your modem.
In addition, the AT speed and parity are stored, according to the values
used at the time the command is issued.
------------------------------------------------------------------------
&W0 Store the Active Profile into Stored Profile 0
&W1 Store the Active Profile into Stored Profile 1
------------------------------------------------------------------------
我认为这几乎涵盖了Hayes制造的所有调制解调器，所以我认为这可能是我得到的最正式的参考.
I assume this covers more or less all modems made by Hayes, so I think this probably is the most official reference I get.
TIA/EIA-602是V.25ter/V.250的(较旧的)替代规范，标题为数据传输系统和设备-串行异步自动拨号和控制".根据关于Hayes的信息"命令集:
An (older) alternative specification to V.25ter/V.250 is TIA/EIA-602 with title "Data Transmission Systems and Equipment - Serial Asynchronous Automatic Dialing and Control". According to Information On Hayes command set:
，但规范未涵盖所有内容，TIA/EIA-602也被称为最小AT命令集".根据弗兰克·达达(Frank Durda)的 AT &&前缀命令集参考
but the specification is not including everything,TIA/EIA-602 is also referred to as the "Minimal AT Command Set".According to Frank Durda's AT Ampersand-Prefixed Command Set Reference
然后我将其解释为意味着Hayes Smartmodem定义了AT&W，但EIA/TIA-602不导入(很可能)，或者它是在EIA/TIA-602创建后的某个时候引入的(否).很有可能).
Which I then interpret to mean that either Hayes Smartmodem defines AT&W but EIA/TIA-602 does not import it (most likely) or that it was introduced after the creation of EIA/TIA-602 at some point (no so likely).
任何有权访问Hayes Smartmodem原始手册的人吗?
Anyone that has access to an original Hayes Smartmodem manual?
这篇关于哪个标准指定了AT& W AT命令?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
