ZSTART.COM is another DSZ interface program allowing use of Chuck Forsberg's
DSZ zmodem protocol with Telix 2.12 and other comm programs that have a run
editor option (Alt-A in Telix).  All that's necessary is to type in ZSTART.COM
as the editor name in the setup menu.  Then to use, press Alt-A to start a
zmodem transfer after the normal transfer request from your comm program.

This program is very small as it was coded in assembly and the only DSZ
commands built in (default) are "rz" and "sz" for receiving and sending with 
the zmodem transfer protocol.  This does not, however, prevent you from using
other DSZ commands (see DSZ.DOC for available commands).

ZSTART looks for command files RZ.CMD and SZ.CMD which can contain your choice
of command strings - RZ.CMD for downloading (receive) and SZ.CMD for uploading
(send).  If the command files are found, their contents will be used as the
command line to DSZ.

Port 1 is the default comm port used by DSZ.  I need to use port 2 and I like
to download and upload to/from separate directories.  This requires that my
command files contain:
                      File      --          Contents
                     ==========================================
                     RZ.CMD     --   port 2 rz \comm\download
                     SZ.CMD     --   port 2 sz \comm\upload\

The maximum number of characters that will be read from a command file is 55.

I wrote this interface for my own use, but I'm offering it to anyone for use
at their own risk.  Of course, I don't know of any bugs and I would like to
hear if any are found.  Please leave me a note on Charisma BBS (415) 349-6576
or Toad Hall BBS (415) 595-2427.

History:
11-22-87 revision -  v 1.10    As a safety measure, the program now asks
         ' *ALL* files ? - y[n] ' if you just hit ENTER at the request for
         Filename(s) to send (upload).
         Apparently if you do not specify a filename, DSZ will send all the
         files in the directory specified by the pathspec or all the files in
         the current directory if no pathspec is given.  This can be handy if
         you do want to send a group of files and they are in their own
         directory.  But not knowing this can cause problems and that's the
         reason for asking you to confirm.  An ENTER at the default 'n' will
         take you back to the Filename request, or if you really want, a 'Y'
         will start an upload of 'ALL files'.

12-03-87 revision -  v 1.20   Return null error code on termination for
         ProComm.

  1-1-88 revision -  v 1.30   Now looks for DSZ.EXE if DSZ.COM is not found.
