a1 and b1 are the incoming phone lines (e.g. outside line or private branch ex-
change).
a2 and b2 are used to connect a phone in series. In idle state, they are connected to
a1 and b1 via a loop current connector. a2 and b2 are disconnected as soon as the
modem occupies the line.
4.4 User Profile
The modem offers a choice of profiles:
¾Default factory setting:
The default factory settings enable you to achieve a fixed
defined basic state of the modem. Starting with this “ba-
sis”, you can customize the modem according to your re-
quirements.
¾User profiles 0 and 1:
You can save configurations in the user profile, which may be
re-used for certain purposes.
A part of the S registry is saved in each profile. In the descrip-
tion, the affected registries are marked with an “*” in the S
registry.

4.5 Configuration Software HSComm
The configuration of the modem takes place via AT commands which are entered
by a terminal program or a control program in the form of character sequences. For
a simple set-up, all basic functions of the HELMHOLZ modem 56k 4.1 can be en-
tered without knowing the individual commands and their parameters, using the
configuration software.
The software can be installed on all common Microsoft Windows operating sys-
tems. A terminal window to enter commands directly is available.
4.5.1 HSComm Operation
At the start or via the menu Device -> Read settings, HSComm verifies the connected
device and displays the device name and the firmware in the program window. By
default, only those settings can be selected which are implemented in the identi-
fied device.
The buttons in the right column can be used to select the current settings, to reset
the device to the saved settings (Reset), or to set the factory settings (default val-
ues).
The selected configuration of the parameters is only sent to the modem after you
click the button SEND.
File menu: Configurations can be saved as files and re-loaded at a later date.
When an error occurs while transmitting a configuration to the modem, these are
displayed in the Error menu.
Hitting the key F1 will automatically display a help window regarding the cur-
rently selected topic.
