在Shell脚本中使用AT命令 [英] Use AT command in shell script

问题描述

我正在使用gsm调制解调器通过终端发送短信，没有问题，但是我想编写一个shell脚本(由php调用)，并且我想知道如何在其中插入AT命令.

I'm using gsm modem to send sms, via a terminal there's no problem but i want to write a shell script (called by php) and i want to know how insert AT command in.

示例:

• 调用脚本.sh
• 脚本打开minicom(sudo ..)
• 类型:AT + CMGS ="num" + ENTER +消息" + ctrl + Z 并将短信发送到号码.

• call the script.sh
• the script open minicom (sudo..)
• type : AT+CMGS="num" + ENTER + "Message" + ctrl+Z and send the sms to the num.

谢谢 维克多

推荐答案

暂时 ¹ 我认为您最好的选择是使用编程语言

For the time being¹ I think your best option here is to use the programming language expect. It is written to monitor growing text output and support scenarios like

1. 等待字符串"Username:"出现在输出中.
2. 发送字符串"my_name".
3. 等待字符串"Password:"出现在输出中.
4. 发送字符串"my_secret_password".

1. Wait for the string "Username:" to appear in the output.
2. Send the string "my_name".
3. Wait for the string "Password:" to appear in the output.
4. Send the string "my_secret_password".

发送AT命令并等待响应非常相似，因此这是绝对可行的.当我在爱立信工作时，我们编写了一个测试套件，期望它可以发送AT命令并解析日志文件以运行测试.

Sending AT command and waiting for the response is very similar, so this is absolutely doable. When I worked at Ericsson we had a test suite written in expect that sent AT commands and parsed log files to run tests.

¹ 作为我的 atinout 程序的伴侣，我已经开始编写一个程序来发送命令AT + CMGS及其有效载荷正确.但是除非您非常非常有耐心，否则您不应该等待此操作完成.

¹ As a companion to my atinout program, I have started to write a program to send the command AT+CMGS and its payload correctly. But unless you are very, very patient you should not wait for this to be finished.
