如何串行发送AT Command?我的意思是在下面给出的串行程序中如何以及在何处插入AT命令:

I need to send sms to my gsm modem - SIM300 V7.01.

How to send AT Command serially? I mean how and where to insert the AT Commands in the serial program given below:

#include <reg51.h>
void SerTx(unsigned char);
void main(void){
TMOD=0x20; //use Timer 1, mode 2
TH1=0xFD; //9600 baud rate
SCON=0x50;
TR1=1; //start timer
while (1) {
SerTx(‘Y’);
SerTx(‘E’);
SerTx(‘S’);
}
}
void SerTx(unsigned char x){
SBUF=x; //place value in buffer
while (TI==0); //wait until transmitted
TI=0;
}

如果程序错误，请给我合适的解决方案.

推荐答案

这看起来像是8051微控制器的代码.首先阅读文档或教程(Google提出了此 [ ^ ]网站)

我不再记得如何配置串行端口，您将不得不查找适当的寄存器设置.
除此之外，您的代码看起来还可以，请尝试使用AT命令序列的每个字符调用SerTx.

This looks like code for an 8051 microcontroller. First read the documentation or a tutorial (Google came up with this[^] site)

I no longer remember how to configure the serial port, you''ll have to look up the appropriate register settings.
Other than that, your code looks OK, try calling SerTx with each character of the AT command sequence.
