General questions
How can I send AT commands to the ISDN terminal adapter?
A communications or terminal program such as ELSA ZOC
is necessary to
address the ISDN terminal adapter from your PC. After starting
ELSA ZOC
, you will be
able to send individual AT commands to the terminal adapter. These are sent to the
ISDN adapter via the serial interface of your PC.
How do I configure the terminal adapter for the D channel protocols for
Euro-ISDN (DSS1) or national ISDN (1TR6)?
ELSA ISDNconfig
is a utility program which permits the simple, convenient
configuration of your
ELSA TanGo 1000
. It can be used to set the D channel protocol
for example, or to enter the MSN or the EAZ.

changed the configuration in the mean time, you can restore the ISDN adapter's
factory defaults with the command
AT&F

AT*W
.
How can I accelerate data communications programs such as the
CompuServe Information Manager under Windows?
As the owner of a buffered UART 16550 interface chip, you should open the
SYSTEM.INI file in your Windows directory and make the following entry in the
[386Enh] section:

Replace the placeholder x with the number of the correct serial port (e.g.
COM2FIFO=1; in this case, '2' stands for COM port 2). In the event that your computer
does not have a UART 16550, we recommend the upgrade of your serial interface.
My ISDN terminal adapter no longer accepts AT commands. Is it incorrectly
configured or defective?
If AT commands do not appear on your screen and are not executed by your terminal
adapter, this can have a number of causes. You should check the following settings:
