   Bug fixed

   1. V.22 bis calling tone ( 1300 Hz, some peple say V.25bis guard tone ) can
      trig U-1496 modem to switch to fax receiving. This bug fixed.

      Only 1100 Hz ( FAX calling tone ) will switch modem to fax receiving.
      Thers is no need to set bit 7 of s41 now.

   2. Two multi-auto modem handshake to 2400 or fail if answer end delay to
      answer ( Example: answer machine ahead ).

   3. Fax calling tone stop when the other end off hook or voice answer.


   New Change

   1. 100 ms delay changed to 480 ms delay after dial tone detected to dial
      first digit. Some slow PBX need this delay to handle first digit.
