/* 
InOut.c: Reads/Writes the byte data via the COM port.

Compiler: BC++ 3.1,
          Turbo C++ 1.01 (3.01)

Compile mode: Large

Project: InOut.C
         ..\..\Lib\uPAC5000.lib

Hardware: uPAC-5000

Description
    This demo use block style loop to read data from COM Port, and exit the loop if press the ESC key.
    
    ToCom() and ToComBufn() will write byte data to COM port,
    ToComStr() will Send out a string (end with '\0') to COM port.
    In this demo, it also shows how to use diffenent format of byte data,
    such as unsigned char data (ASCII) 'A' will represent as 0x41 in hex format or 65 in decimal format.
