         Audiometer sample program source files
                      11/10/92 -med


The source files have been compressed into packed archive
form in orderto save space on the disk. You can unpack 
the source files with the UNPACK program that is provided.

Copy the files UNPACK.EXE and SAMPLES.PAK to your hard disk, 
or to a freshly formated floppy disk. Then run the unpack 
program to unpack the source code by entering the following 
at the DOS prompt:

   UNPACK SAMPLES.PAK

PASCAL.TXT   - documentation about the Pascal programs


------------------------------------------------------
Note that these programs require Borland's Turbo Pascal
to compile. You may use the Windows version, or the MSDOS
version. The compile directives in the files automatically
select the appropriate code for the target system. 

The Windows version of the programs are very simplistic 
in order to maintain the compatibility to MSDOS. 
The DOSCRT unit does most of the work to provide the 
emulation of the MSDOS enviornment. You can either 
continue to use the DOSCRT unit, or you can start with 
your own Windows enviornment. The audiometer communication
routines do not rely on DOSCRT to do their work. 
Do note though that they require a special compiler switch 
to work in Windows mode. This slows things down a bit, but 
it is generally not a limiting speed factor.

The programs listed require that the FRYERS driver be loaded 
to be able to communicate with the audiometer. The FRYERS 
driver must be loaded before the program is run. FRYERS.COM 
is a TSR program that will stay in the system until you 
turn the power off or reboot your computer. For Windows 
operation, FRYERS must be loaded before WIndows is started. 
Additionally, for Windows operation or any other protected 
mode enviornment, you must use Version 3.00 or later of the 
Fryers program which allows use in protected mode operation.
