Installation of the local modem
If you have already installed a modem under Windows, you can mostly
use it for the remote maintenance. In this case you can skip this step
and use the already installed modem.
Plug&Play modems will be detected automatically after they have been
connected to the PC. But you need the driver supplied with the modem.
None Plug&Play modems can be installed manually via Control Panel >
Phone and Modem Options > Modems. The supplied driver is needed
here, too. Alternatively, you can use one of the standard drivers supplied
with Windows (e.g. Standard 28800 bps Modem). You can choose the
installed Modem in the parametrization of the programming software.
You choose the installed modem in the programming software during
connection establishment.
