ZModem Setup Help

        This Module Allows you to setup the various Features of ZModem.


        What is Zmodem?

        Zmodem is a file transfer protocol that offers the best overall mix
        of speed, features, and tolerance for errors.  The Zmodem protocol
        has many options and clearly was meant to have lots of room for
        growth.

        The purpose of the development of Zmodem was to provide a durable
        protocol with strong error recovery features and good performance
        over a variety of network types (switched, satellite, etc.).  It
        has generally achieved these goals and, therefore, should be the
        protocol of choice whenever possible.


        Simply move the 'X' to the desired selection, or type in the value, and
        proceed to the next field.  As you move from field to field you will
        notice the messages at the bottom of the screen will change.  These are
        quick help  messages.


        Keyboard interaction
        --------------------

        TAB/Shift-TAB           : Moves you from one option to another option.

        Enter                   : Moves you from one option to another option.

        Up/Dn Cursor Keys       : This will move the 'X' placed next to the
                                  selected item in this field.

        Left/Right Cursor Keys  : Moves you left and right in the field.

        Home                    : Places you at the begining of the field.
 
        End                     : Places you at the end of the field.

        Escape/Alt - C          : Aborts and Exits this Module

        Alt - O                 : Saves all changes and exits this module.

        Alt - H                 : Provides help for this module


        Mouse Interaction
        -----------------

        Selecting an option: Left Click on the option you desire to change. If
                             it is button field, it will move the 'X' to the
                             value you click on.  If it is a string field,
                             it will place the cursor at the start of that
                             field.

        Saving changes     : Left Click on the OK

        Help               : Left Click Help

        Aborting           : Left Click Cancel or '■'

1 - Maximum Packet Size

        The maximum number of data bytes in any one data subpacket.

2 - Window Size

        This is an estimate of the turnaround delay in a Zmodem protocol.
        Turnaround delay is the time, in milliseconds, required for the remote
        system to acknowledge the last block. Generally, Zmodem doesn't have
        any turnaround delay at all, since its data subpackets do not require
        an acknowledgement. However, some Zmodem implementions may request such
        acknowledgements.

        This setting would be useful when dealing with satellite transmissions


3 - Time Out Period

        This value describes how long Zmodem will routinely wait for the next
        character in a sequence. It does not control how long Zmodem will wait
        for the initial handshaking packet.

4 - Time Out Tries

        This value describes how many time outs Zmodem will sustain before
        aborting the session.

5 - Save Mode

        These constants are used to specify the desired file management options
        governing received files. The default setting is Transfer Always.


6 - Resume Downloads

        Turn file recovery on (will be ignored if dest file doesn't exist).
