sending a bit of a char ro any port pin

yavuz,
obviousely, you cannot infinitely increase the size of your buffer! that is a big problem indeed! I have corrected your code below to make is circular buffer. there are of course many other options!

char MyBuffer[20],output;  // buffer and current display output
  int i=0;   // counter

  while (output != '$')  // "$" key is the end of dos string
  {
    MyBuffer[i % 20] = output;
    i++;
  }

  }

the modulus operator is just about the slowest thing you can use in '51 c code.

thus, make circular buffer size a power of two and then the access is
... [index & (BUFFER_SIZE - 1)]

yap, correct. but I was trying to save lives....

Modulus and circular buffers aside ...

The code is incomplete, non-functional, and rubbish anyway.

And it doesn't even answer the OPs original question!

well, that's why I wrote
I cannot help him with that, as I don't know the processor (do you...?)

This is a funny thread. The answer to the OPs question is available in the fifth post. After that follows incomplete code that tries to answer a question I haven't seen.

What this thread needs, is for the OP to read post #2 and come back with more info, i.e. may the original question be the result of a misunderstanding.
