1. Command line parameters
==========================


load itkdm.nlm  PORT=<IO-Port> MEM=<Memory Address> CC=<Country Code> 
                XL=<Transmit Level>",


Port specifies the I/O-Port selected by the dip-switches on the ITK DigitalModem. 
     For a description of the configuration of this parameter refer to 
     "4. List of I/O-Ports and dip-switch configuration".


MEM  specifies the shared memory area for the communication between the 
     ITK DigitalModem and the PC. For all possible values refer to 
     "5. List of usable shared memory windows".

CC   specifies the country you are operating your ITK DigitalModem board in. 
     For a list of supported values see: "6. List of Country Codes".

XL   configures the transmit level for the output signal of the ITK DigitalModem. 
     Normally this parameter need not to be used as the default is set by the 
     country code. You can specify any hexadecimal value 0..9,A..F. 
     The lower the value the louder is the signal.

For simple use we generated a batch called itkdm.ncf to handle the 
standard values.



2. List of I/O-Ports and dip-switch configuration
=================================================

Before plugging your ITK DigitalModem board into your PC you should 
find a free I/O-Port and adjust the dip-switches on the ITK DigitalModem.

This table lists all available Port configurations.

3. List of usable shared memory windows
=======================================

In the command line for the ITK DigitalModem board you must specify a 4KB 
shared memory window. 

Here is a list of all available memory addresses:
     x0000
     x4000
     x8000
     xC000
with x = A,B...F

e.g. you can use address D0000 


4.  List of Country Codes
=========================

For most countries specific defaults are configured automatically by using 
the country code.

This list shows all available configurations:

     Country            Country code
