ATI Commands & Rs232 - PIC 18F8722
PostPosted: Wed Jul 04, 2007 4:57 pm     Reply with quote
Hi,

PLEASE HELP!

I'm trying to implement a timeout on serial port if I don't get a character after say 30 seconds. I've looked at the timed_getc() example, this is fine upto 1/2 second but if I increase this it never returns.

I'm using the following to read the ATI response from a modem.

fprintf (rs232stream,"ATI4\n\r");

while (1)
{
c = fgetc (rs232stream);
fprintf (hyperterm, "%c", c);
}

I would love it if I could replace the above with a timeout version which works - many thanks

What about this thread that you started two weeks ago ?
At the end of the thread you said everything is working fine.

Hi PCM Programmer,
That wasn't me, but thanks for posting the link. I'm new to PIC programming, I was thinking on the same lines of the example but don't know how to do it.

My question is on the RTCC timer, can you let me have an example of a variable time out function such as:


Code:
void timeout ( int16 num_secs)
{
   // this will wait num_secs before timing out

   ...
      code
   ...
}


I'm not completely sure of the best way to do this - thanks

help!
