通过gprs发短信的程序，重点在设置串口属性，比如硬件流控，等等。strcat(gsmMessage, ??\x1a??); 这一句结束短信内容。串口设置的有关语句如下： newtio.c_cflag |= CLOCAL | CREAD | CRTSCTS; newtio.c_iflag = IGNPAR; newtio.c_oflag = 0; newtio.c_lflag = 0; ////non ICANON newtio.c_cc[VINTR] = 0; /* Ctrl-c */ newtio.c_cc[VQUIT] = 0; /* Ctrl-\ */ newtio.c_cc[VERASE] = 0; /* del */ newtio.c_cc[VKILL] = 0; /* @ */ newtio.c_cc[VEOF] = 4; /* Ctrl-d */ newtio.c_cc[VTIME] = 5; /* inter-character timer, timeout VTIME*0.1 */ newtio.c_cc[VMIN] = 0; /* blocking read until VMIN character arrives */ newtio.c_cc[VSWTC] = 0; /* ''\0'' */ newtio.c_cc[VSTART] = 0; /* Ctrl-q */ newtio.c_cc[VSTOP] = 0; /* Ctrl-s */ newtio.c_cc[VSUSP] = 0; /* Ctrl-z */ newtio.c_cc[VEOL] = 0; /* ''\0'' */ newtio.c_cc[VREPRINT] = 0; /* Ctrl-r */ newtio.c_cc[VDISCARD] = 0; /* Ctrl-u */ newtio.c_cc[VWERASE] = 0; /* Ctrl-w */ newtio.c_cc[VLNEXT] = 0; /* Ctrl-v */ newtio.c_cc[VEOL2] = 0; /* ''\0'' */ int main(void) { int fd; int nread,nwrite,i; char buff[32]; char reply[128]; char gsmMessage[20] = ??Hello!??; if((fd=open_port(fd,2))<0){ perror(??open_port error??); return -1; } if((i=set_opt(fd,115200,8,''N'',1))<0){ perror(??set_opt error??); return -1; } printf(??fd=%d\n??,fd); memset(buff,0,sizeof(buff)); buff[0] = ''A''; buff[1] = ''T''; buff[2] = ''\r''; nwrite = write(fd,buff,3); printf(??nwrite=%d,%s\n??,nwrite,buff); memset(reply,0,sizeof(reply)); nread = read(fd,reply,sizeof(reply)); printf(??nread=%d,%s\n??,nread,reply); memset(buff,0,sizeof(buff)); strcpy(buff,??AT+CMGF=1??); strcat(buff,??\r??); nwrite = write(fd,buff,10); printf(??nwrite=%d,%s\n??,nwrite,buff); memset(reply,0,sizeof(reply)); nread = read(fd,reply,sizeof(reply)); printf(??nread=%d,%s\n??,nread,reply); memset(buff,0,sizeof(buff)); strcpy(buff,??AT+CMGS=??); strcat(buff,??136??); strcat(buff,??\r??); nwrite = write(fd,buff,strlen(buff)); printf(??nwrite=%d,%s\n??,nwrite,buff); memset(reply,0,sizeof(reply)); nread = read(fd,reply,sizeof(reply)); printf(??nread=%d,%s\n??,nread,reply); strcat(gsmMessage, ??\x1a??); nwrite = write(fd,gsmMessage,7); printf(??nwrite=%d,%s\n??,nwrite,gsmMessage); memset(reply,0,sizeof(reply)); nread = read(fd,reply,sizeof(reply)); printf(??nread=%d,%s\n??,nread,reply); close(fd); return 0; } |
