C167 reading/scanning input from GSM module from RS232

Andrew Young

Hello,
I am a novice in C language and have been trying to find a method of reading/scanning input from GSM, then comparing it against a text (e.g OK or ERROR). Then if true set a break.

I have tried scanf with no avail. I have also tried reading string which works but am unsure how to compare with my text.Has anyone any advice with what function would be useful?

Any replies greatly appreciated.

    I think the following will do what you want:

    char arr[5];
    int result;

    gets(arr,4); //Note non-standard Keil gets()
    puts(arr);
    result=strcmp("Ok",arr);
    printf("Result=%d\n",result);

    There are many mistakes in the code you posted - you really need to work on your 'C' a bit with a good book.
