Serial Communication through ISDN/CAPI?

[a***@gmail.com]

I am working on updating my application which communicates with
external devices through serial ports or lets me call a GSM modem
through an analog modem or a connected (serial) cellphone where the
GSM modem identifys my callerid and than allows me to transfer data to
and from my devices.

Now the question came up to support ISDN to call through the software
to connect to the devices.

My application is all built up to use serial ports but as far as i
found out, ISDN doesn't exactly provide me with a real or virtual COM
port like an analog modem which i could easily handle with AT commands
and communicate right through its port.

Can ISDN/CAPI provide a serial port for my use and can i handle it in
a similar way?

Any help appreciated.

Maybe cFos[1] is the right thing for you. It provides virtual COM ports
for ISDN.

ISDN and CAPI doesn't know anything about serial ports but
most (consumer-) cards you buy come with a CD containing
drivers that install virtual COM-ports for different types
of ISDN-connections (PPP, etc.)

AFAIR AVM Fritz allows you to install a lot of additional ports.
