如何用C语言的Helloworld那种程序操作串口呢？有木有方法。楼主经过了探索发现是有的。
#include <stdio.h>
unsigned char wbuf[1600];
unsigned char mingling[]="mode com3:baud=9600 parity=n data=8 stop=1 to=off xon=off";
int main(void)
{
FILE* portfp;
system(mingling);
portfp = fopen("com3","wb+");
printf("Hello world");
system("cls");
if (NULL == portfp){
printf("open com port fail!\n");
exit(0);
}
fread(wbuf, 1, 1600, portfp);
printf("%s",wbuf);
fclose(portfp);
}
