do{;}while (!TI);will wait forever until TI is set.
Thus, for your first character, your code must set TI to get things started. So I wonder if the compiler C51 assumes I am using interrupt??? Absolutely nothing to do with the compiler whatsoever. Your source code is just not equivalent to your assenbler. They are different so, naturally, they behave differently! If you want the behaviour to be the same, you must re-write the 'C' to do what you require. |
