[問題] Linux RS-232 程式設計
各位大大好，我想請問一下就是說
我現在要用RS-232來做一個資料的傳送，
然而我預計要傳送29筆資料出去，但是接收端卻只能接收前8筆資料或前9筆資料，
之後的資料就都不見了，所以想請問這大概會是哪裡有問題，謝謝!
收資料方面利用終端機收。
以下是我的傳送端程式碼
int fd,res=0;
struct termios oldtio,newtio;
int s1[29]= {0x01,0x10,0x17,0x70,0x0,0xa,0x14,0x0,0x81,0x0,0x81,0x0,
0x83,0x0,0x99,0x0,0x0,0x0,0x80,0x0,0x0,0x0,0x0,0xff,0xff,
0xff,0xff,0xb3,0xdd};
char s2[29]={0};
fd = open (MODEMDEVICE, O_RDWR|O_NOCTTY);
tcgetattr (fd, &oldtio);
bzero(&newtio, sizeof(newtio));
newtio.c_cflag = BAUDRATE | CS8 | CLOCAL |CREAD;
newtio.c_iflag = IGNPAR;
newtio.c_oflag = 0;
newtio.c_lflag = ICANON;
tcflush(fd, TCIFLUSH);
tcsetattr(fd, TCSANOW, &newtio);
for (int i=0;i<29;i++)
{
s2[i]=s1[i];
}
res=write(fd, s2 ,29);
tcsetattr(fd, TCSANOW, &oldtio);
