在通过ATDTnnn 发布之后,Mom给予ERROR。
原标题:Modem gives ERROR after issuing ATDTnnnnnnn

我试图使用通过USB连接的当地电解调器,使用一条遥远的电解调器。 方案拟订语言是VB。 NET和我正在使用<代码>Serial Port控制,与电解调器交谈。

来文如下:

I sent:ATZ0[CR]

模式答复:ATZ0[CR][CR][LF]OK[CR][LF]

我随后试图删除几个方面:

页: 1 有效数目

该模型对应:ATDTnnnn[CR][LF]ERROR[CR][LF]

所有其他指挥部似乎都没有工作问题。

用于电解器的是多技术MT5634ZBA-USB-V92

If I use hyperterminal and type the same commands in it works as expected and dials the number, so it must be something I am doing in my code, possible some setup in the SerialPort control

我已就此发表自己的回答,即:<代码>AT&D0至表格。 上述指挥部门目前正在开展工作。

最佳回答

我经过许多小时的实验发现,签发了<代码>。 AT&D0 (Ignore DTR sign)tor before ATDT, 即该模式不再采用,而是按预期将远距离调制成。

I am still a little confused why typing the commands into hyperterminal worked without having to issue AT&D0 - does anyone know if hyperterminal is issuing commands silently?

问题回答

I haven t issued AT commands for about 12 years, but what I remember was that you needed to read the manual specific to the modem because all the AT commands were different for each brand.

通常,如果你不得不去除,你不得不将“1”除在外线,在你把其余部分分开之前暂停使用。 通常,在发出指挥命令之间,你常常不得不在你的拨号上稍加等待。 从记忆中,这些是“W1”、“W2”等。

因此,为了拆开一条外线(“1”),然后是电话号码(“123456”)。

ATDT1W3123456[CR][LF]

时间已很长,因为我这样做:

Also, from memory, AT&D0 was something like "reset the modem state" so we always started our scripts with that command.

我想看到你的法典能够更好地理解这个问题,但作为一个开端,我试图派人去。

ATDTnnnnnnnnnn[CR][LF]

你们是否试图与[LF]而不是[CR]结束“ATDT”?

ATZ0 returns some stored configuration to use. Maybe there is something that cause problems. You can print if by command:

AT&V[CR]

提炼厂重建指挥部

AT&F[CR]

And then:

ATDTnnnnn[CR]
