XLink85 v1.1 - PC to TI-85 calculator link program for Linux and MS-DOS
               By Jani Halme (jaadha@utu.fi)

INTRODUCTION
------------

  XLink85 is a software package for transferring files and backups 
between a Texas Instruments TI-85 calculator and a PC running Linux
or MS-DOS as operating system. XLink85 is released under GNU General
Public Licence (see file 'COPYING'), so there is ABSOLUTELY NO WARRANTY
on it's operation. But you get the source code so be happy! :)


REQUIREMENTS
------------

  Your system must be an Intel x86 -series PC running Linux or MS-DOS
(or possibly also some other *nix system, such as 386BSD). You also
need read/write access to /dev/port in order to transfer data through
the link cable. I've also added some preprocessor commands into the
source code, so that the program compiles fine in MS-DOS using the
DJGPP v2 compiler by DJ Delore.


CONFIGURING
-----------

  Edit the file 'config.h' to match your system configuration and run
'make clean ; make all'. When editing 'config.h', note that LPT1 in
MS-DOS isn't necessarily /dev/lp0 (see 'config.h' for more info).
If you are compiling to MS-DOS, try checking your port configuration
with for example 'c:\dos\msd.exe'.


USAGE
-----

  Receiving data:

	Run 'recv85' and start the transfer from the calculator.

  Sending data:

	Do '[2nd],[LINK],[F2]' on the calculator to make it listen
	for data. Then type 'send85 filename [filename ....]' to
	start the transfer.
