Disable MNP Level 4; retransmitting the larger Lev el 4

Some earlier 2400 bps MNP modems, not made by U.S.
Robotics or Microcom, were not fully compatible with
the MNP protocol. If you have difficulty making a
successful 2400 bps MNP connection with a remote MNP
modem, it may be because of this incompatibility. Set
S15 to 64 and try again to make the connection.
