IPXFER is a command line IPX File Transfer Program that eliminates the hassle
of swapping floppies when exchanging PWADs (or any other file type for that
matter).

IPXFER consists of 3 files:

   SENDNET.EXE  - File sendning program
   RECNET.EXE   - File receiving program
   CLOSES.EXE   - Closes the IPX sockets used by IPXFER in case you have
                  to use CTRL-BREAK to get out of a session.


The only parameter for SENDNET is the file specification of the files you
wish to send (Wildcards are OK).  DO NOTE-  SENDNET will not allow you
to specify a path to the files you wish to transfer.  You must be in the
directory from which you want to send.  (This is something later versions 
will fix).

For RECNET, you can specify the -SKIP parameter,  this will cause IPXFER
to ignore files that already exist at the destination.  This saves a lot
of time if you have several duplicate files on either hard drive.

CLOSES has no parameters.

Changes from v1.1:

   -Added the -SKIP parameter to RECNET so that you can skip files that
    already exist at the destination.
   -Both SENDNET and RECNET have built in 64k file buffers to help improve
    performance.
   -The protocol has been rewritten to dramatically improve data throughput.
    On smaller files, IPXFER 2.0 is roughly 5-10 times faster than 1.1.  On
    large files (such as DOOM.WAD), it is roughly twice as fast.
   -New display screens (whoopie...)
   -Improved protocol stability.

Changes from 2.0:

   -Fixes a small timing problem in 2.00 that would occasionally cause
    a lockup to occur during multiple file transfers.
   -Adjusted the file buffering so that file transfers seem less choppy.
   -Will no longer allow boneheads that wish to ignore my warnings about use
    under Windoze to do so.  IPXFER will simply give you a little message
    about being a DOS app and quit on you.

NOTE:  Unlike previous versions, IPXFER 2.0 & 2.1 are NOT downward compatible 
with earlier versions.  Using a copy of .99b, 1.0 or 1.1 with 2.0+ will result 
in serious data loss.

Should be added to future versions:

   -Capability to specify a directory path on the command line of SENDNET.
   -Capability to send entire directory trees, rather than just one directory
    at a time.
   -One station operation.  Run a shell on the local terminal and a request
    processor on the remote computer and do all the work from the local one.
   -Maybe a Windoze version if I get enough interest in one.


Winoze Users:

   -IPXFER for DOS is >>>NOT<<< designed to be used under Windows.  If
    you do feel it necessary to blow off this warning, be my guest.  IPXFER
    will now give you a wonderful little message if run under windows and
    quit on you.

Data Throughput:

   When using computers running as fast or faster than a 386DX/40, typical
   throughput was around 120k - 150k per sec   (sustained transfer).  When
   sending files smaller than 16k, burst thoughput reaches around 400k per
   sec.  Disk caches will also dramaticall improve performace.

   Note: These speeds were achieved using 16bit NE2000 EtherNet cards that
         have a transfer speed of 10MBits / Sec and Western Digital 212Mb
         hard drives that have a data trasnfer rate of around 1Mb / Sec.

   ARCNET Users:  Expect speeds of around 60k-80k per sec.  (ARCNET cards
                  typically have a transfer speed of around 2.5MBits / Sec.)

Registration:  Well, I have put enough time into IPXFER that I think it is
a decent enough program to ask for registration.  If you enjoy this program
and would like to continue using it, a registration fee of $5 would be
appreciated.
