C serial port programming

I have a send.c.
I send: "7E 40 09 00 BE EF 05 7D 5D 06 01 02 03 04 05 7E".
But at the read.c, I want "Proto = 40" as the output.
Currently in my program, the output is:
"Proto 40 09 00 BE EF 05 7D 5D 06 01 02 03 04 05 7E".

Here is my sample code:

Code:

---

int bufsize = 46;
        int k=0;
        int i;
        for (i=0;i<bufsize;i++)
        {
            if (buf[i]=' ')
        {
            k++;
        }
        if (k==3)
        {
            printf("Proto %s\n", buf);
        }

---

Please help me...

You have the same data over here as well.

And a lot more code to show for it.

But regrettably, it doesn't have any code tags, so it's going to get ignored.
