ARM开发板上通过gprs发短信

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' */
