如何在C#中通过串行发送CTRL_Z? [英] How to send CTRL_Z through serial in C# ?

问题描述

大家好，

我正在一个项目中，使用GSM调制解调器从我的电脑向手机发送SMS消息.

iam working a project to send SMS messages from my pc to mobiles using GSM modem..

为此，我必须在超级终端中编写以下命令.

in order to do that i have to write the following commands in hyper terminal..

AT< cr>

AT <cr>

调制解调器的响应正常

AT + CMGF = 1

AT+CMGF=1

来自调制解调器的响应是可以的

responce from the modem is OK

AT + CMGS =我的手机号码"

AT+CMGS="my mobile number"

来自调制解调器的响应是>

responce from the modem is >

然后我编写消息，然后按CTRL_Z，然后按Enter

then i write the message and press CTRL_Z then Enter

调制解调器的响应正常

问题在于，尽管命令在超级终端中有效，但在C#中它没有发送消息.

The problem is that in C# it is not sending the message although the commands worked in Hyper terminal..

在C#中，当我发送CTRL_Z时显示[]符号，尽管在超级终端中它显示->箭头.

In C# when i send CTRL_Z in shows me [] symbol although in hyper terminal it shows -> an arrow..

如何在C#中正确发送ctrl Z.

how to send ctrl Z correctly in C#..

我尝试了以下操作，但没有成功

i tried the following and they didnt work

serialPort1.Write( " \ u001A; );

serialPort1.Write("\u001A");

serialPort1.Write(26 + "'' );

serialPort1.Write(26+"");

serialPort1.Write( " CTRL-Z; );

serialPort1.Write("CTRL-Z");

???

如果您有任何想法请帮助我

推荐答案

串行端口具有写入字符数组的功能，因此请尝试以下操作:

Hi,
Serial port has a function that writes an array of chars, so try this:

字符 [] arr = 新 字符 [1];

char[] arr = new char[1];

arr [0] =( char )26; //Ctrl-Z的ascii值

arr[0] = (char)26; //ascii value of Ctrl-Z

m_SerialPort . 写 ( arr ，0， 1 ); //array，start，length

为我工作...

m_SerialPort.Write(arr,0,1); //array, start, length

worked for me...
