UPDATE# OTHER FILE TRANSFER IMPROVEMENTS

 . Bigger file transfer window sizes and packet buffers, depending on
   available memory.  Packets may be up to 9024 bytes in length, and the
   window can contain up to 31 packets of the maximum length.  Use the 
   regular commands to select these sizes: SET RECEIVE PACKET-LENGTH and
   SET WINDOW.	Also see the Memory Management section of KERMIT.BWR
   (MSKERM.BWR). 

 . Locking shifts for more efficient transfer of 8-bit text on 7-bit
   connections (important for Cyrillic, Hebrew, and Japanese text).  New
   command:

   SET TRANSFER LOCKING-SHIFT { OFF, ON, FORCED }
     The default setting is ON, meaning that MS-DOS Kermit will attempt to
     negotiate use of this feature with the other Kermit if the parity is not
     NONE, in which case locking shifts will be used if the other Kermit
     agrees (C-Kermit 5A and IBM Mainframe Kermit 4.2.4 will agree, others
     will not).	 OFF means don't negotiate locking shifts, and FORCED means to
     use them regardless of negotiations.

 . Dynamically variable packet length to adapt automatically to changing noise
   conditions.	This happens automatically when MS-DOS Kermit is sending
   files.  No commands are needed.  If packets are damaged by noise or
   timeouts occur, MS-DOS Kermit cuts the packet length in half and then
   gradually grows it back to the maximum negotiated size as (and if)
   transmission errors subside.

 . A new file transfer "thermometer", improved statistics reporting including,
   for serial connections only, the efficiency of the transfer expressed as a
   percent.  This is the ratio of actual file characters transferred per
   second to the connection speed.
