// Notes:

// This is a Singleton class.

// LoadEntry() must be called before calling any other
// functions (of course, except Instance()).

// User must delete the instance pointer obtained from
// Instance() when done.

// It is recommended that a user of this class understand
// the structure and content of the "termcap" file.

// Note :  At present, this class doesn't support the
//		  concept of padding dummy characters to handle
//		  different speeds of transmission
