Some datacommunication services like internet, mail, fax, remote
access (RAS)
are only accessible over a com-port device (analog-modem,
external isdn-device).
In many cases, you can only connect to them via their own
dialer-software, which
only allows to select com-ports for dialing up, instead of using
the capa-
bilities of the capi-interface to connect to the
service-provider.
This results in a problem, when trying to use such services over
an isdn-
built-in device or an external device, let's say an isdn-router.
A simple way out of this dilemma is, to use a so called
'cfos'-driver. Explained
quite simplified, this driver converts the isdn-commands to
at-commands and
vice versa, just like having an analog-modem attached to an
unused com-port of
the WINDOWS-pc.
Now it's possible to use the device for your services. The
specified driver
leans on your pc's locally installed 'capi'-.DLLs, which
basically access the
isdn-device. When using remote-capi to access a network isdn
device, like
a BinTec Brick, it's also possible to use this central device for
connections,
without having installed a local isdn device.
There are several cfos-drivers available. We tried out the
cfos-driver from
Lueders und Winkler under Microsoft Windows for Workgroups and
Windows95
successfully (info at http://www.riedlbauer.de), using the BinTec
BRI active
isdn-card (capi) and the BinTec Brick XM midrange modular ISDN
router.
(Check out some isdn-magazine to find out local cfos-dealer).
todo
----
1. verify, that the capi-DLLs are installed and ready
2. install an appropriate cfos-driver and direct the
isdn-interface to an
unused COM-Port
3. direct the dialup connection of your software (internet,
mail,...) to the
installed COM-Port (2.)
