                            ATEST
                   Audiometer Test Program

The ATEST program is provided as a means to test the 
RS232 communications functionality of the audiometer. 

By default, the program will use COM1. If you will be using
COM2, you will need to add a "2" to the command line when 
you start the program. The MSDOS version of the program is 
called ATEST.EXE. The Windows version of the program is 
called WATEST.EXE. If you wish to use COM2 in the 
Windows 3.1 version, you must add the definiton to the 
Properties command line for the file (See WINSTALL.TXT).

The ATEST.EXE program requires that the FRYERS.COM driver be 
loaded in the system first. FRYERS.COM is a TSR that is 
loaded under MSDOS. For Windows 3.1 operation, FRYERS.COM 
must be loaded before Windows 3.1 is started.

The ATEST32.EXE is a 32 bit version of the program that 
allows testing in Windows NT or Windows 95. ATEST32.EXE 
requires that the FRYERS32.DLL file be located in the
Windows directory.

The ATEST program allows you to send commands to control 
the audiometer or read data from it. When the program starts 
up, you can see the list of available commands by entering 
the number '90'. All the commands are based on the FIPP 
number of the command. 

The ATEST program is primarily useful for testing the 
various commands to see how the work before using them in 
your own programs.


Many of the commands read or write extensive amounts of data.
Since it would be difficult to enter all the information
by hand each time, the ATEST program uses data files to 
store and retreive the information.

The ATEST program uses data files with a DAT tag. These 
files are numerous, so they have been stored in a directory 
off the current directory called DAT\. If the directory does 
not exist, ATEST will create the directory when it starts 
up. All DAT files used by ATEST should be located in the 
DAT directory. Many of the ATEST commands will attempt 
to write a DAT file, so the directory must be writable if 
you use those commands. ATEST commands that send data to 
the audiometer do so by reading the data from a DAT file. 
The file must be present in the DAT directory and the data 
valid in order for the command to work. 

The DAT files used by ATEST are standard MSDOS ASCII files.
One line per data point. Each line is followed with a CR/LF.
You can edit the files using a standard ASCII editor just
like you would edit a BAT or CONFIG.SYS file. The EDLIN or 
EDIT editor programs provided with MSDOS will work.

Note: this program used to be called TESTAUD.EXE it was 
renamed to ATEST to reduce the filename size to allow for 
the "32" to be added to the name for the 32 bit version.
