I think hyperterminal deals only in characters.... if you can type the correct ASCII character that corresponds to that bit sequence, then you might be in luck.
In the case of your "01011001" example, just send the character 'Y'. Case in point, yes you can send binary data. Just treat the character data as a 7 or 8 bits of data (depending on terminal settings).
