 EXTERNAL PROTOCOLS & PROTOCOL CONTROL

 The seventh item of the configuration Menu allows you to con-
 figure external protocols, as well as a couple of other set-
 tings.

 An external protocol is simply a file transfer protocol that
 is implemented outside of Telix. You specify the name of the
 protocol, the key used to select it on the file transfer menu,
 and define how it is to be called. Items 'A' through 'D' are
 the definitions for the four external protocols allowed. When
 you select a definition to edit, Telix will ask a series of
 questions:

      Key: This is the key that should be pressed to select
      this protocol when the file transfer menu is displayed.

      Protocol Name: This is the name Telix will display on the
      file transfer menu for this protocol.

      Upload Filename: This is the name of the DOS batch file
      or Telix script file to call when the user selects an up-
      load using this protocol.

      Download filename: This is the name of the DOS batch file
      or Telix script file to call when the user selects a
      download using this protocol.

      BAT or Script: This controls whether the above two file-
      names are DOS batch files or Telix script files.

      DL Name: This option controls whether or not Telix should
      ask for the name of the file when performing a download
      using this protocol. In many protocols, the sender passes
      the name of the file(s) to the receiver, so Telix
      shouldn't ask for the download name.

 See the Appendix titled'External Protocols' for information about
 what information is passed to the batch or script files when an
 external transfer is selected.

 Other settings on this page are:

     E: File xfer disk buf. size This option allows you to set
        the size of the disk buffer used by telix during file
        transfers from 1k to 10k (kilobytes) in size. A larger
        value is more efficient with floppy disk systems, while
        a smaller value can get around problems with disk con-
        trollers or Extended memory use on some hard-disk sys-
        tems.

     F: Relaxed Xmodem timing. This option controls whether or
        not Telix should use relaxed timing when performing an
        Xmodem transfer. When calling some services, this op-
        tion must be turned on because they can not tolerate
        strict timing.

     G: Filename guessing. This option controls Telix's use of
        filename guessing. When you selected a file transfer to
        be performed, telix can often guess the name of the
        file to be transferred, based on your past keystrokes.
        This option may be turned off here. As well, you may
        specify that Telix gives only guesses which it is al-
        most certain are filenames, or gives its 'Best try',
        which may include guesses with extra characters which
        are not necessarily part of the filename.

     H: Zmodem receive crash recovery. When an aborted Zmodem
        transfer must be resumed, this option should be turned
        on. While this option is on, if a file being downloaded
        using Zmodem already exists on the disk (and is shorter
        than the file the sender has), Telix will tell the
        sender to send only the bytes needed to complete the
        file. This option should be used with care. The possi-
        bility exists that a file with the same name but dif-
        ferent contents exists on each system, in which case
        you do not want only some of the data transferred.

     I: Zmodem send crash recovery. When this option is on,
        during a Zmodem upload of files, Telix will try to tell
        the sender to resume aborted transfers. This option
        should be used with care, as some systems do not sup-
        port crash recovery, and will behave unpredictably.

     J: Allow Zmodem 32 bit CRCs. Real speed freaks may turn
        off the use of 32 bit CRC error checking (still quite
        reliable 16 bit CRCs are used instead), to get on the
        order of a quarter to a half of a percent speed in-
        crease in Zmodem transfers.

     K: Zmodem window size. Zmodem normally sends data in
        streaming mode, never pausing unless the other side re-
        quests a resend due to an error being detected. In some
        environments, a pause for acknowledgments can be more
        efficient. The window size (in kilobytes) is the maxi-
        mum amount of data the protocol should seed before
        waiting for a reply. A value of 0 indicates streaming
        mode should be used.

     L: Zmodem file type. This option allows you to specify
        whether the file being transferred with the Zmodem
        protocol is 'Binary', 'ASCII', or 'Either'. Binary
        means that Telix will make sure no end-of-line conver-
        sion is done on files received or sent. ASCII means
        that on a download, as long as the other side doesn't
        override this, Telix will assume the file being re-
        ceived is a text file and will make sure the end of
        each line has a Carriage Return followed by a Line
        Feed, by adding the CR if the file has only LFs at the
        end of each line. An ASCII setting when sending will
        make Telix tell the other system to do end-of-line con-
        version, although the other system  may override this.
        Finally, a setting of Either (the default), will make
        Telix assume the file is binary, unless the other sys-
        tem indicates otherwise. DO NOT use a setting of
        'ASCII' for file that are not ASCII text files, as bi-
        nary files will be corrupted by this option.
