怎麽使用C編寫壹個串口文件傳輸程序

#include

int main(void)

{

FILE *fp;

char temp;

char buf[100];

if((fp = fopen("com3","r")) == NULL)

puts("this way doesn't work!\n");

else

puts("this way works!\n");

while(1)

{

temp = 0;

fscanf(fp,"%c",&temp);

if(temp != 0)

putchar(temp);

else

Sleep(100);

}

fclose(fp);

return 0;

}
