How to? Accessing an installed modem

VB 2005
I'm writing an app that communicates with a device, either on the COM port,
or dials via an external modem via the port.
Once the dial up connection is made, device communications is by regular
serialport.write("Command').

But I'd like to now be able to use an installed modem (internal or external
modem) instead of having to rely on basic external COM port commands, but
don't know where to start.
If this app is currently run on a laptop, the user needs a USB COM port, and
an external modem - but they already have on in the machine.

I'd sure appreciate any suggestions where to begin.
TIA
