Hello

I don't understand what exception do you see.

Possible you set nrCommTAPI.DeviceIndex in incorrect value.

You can try to set nrCommTAPI.DeviceIndex := -1; in design time and select modem at runtime.

Hello Roman,

Simply i created a new borland C++ project and i added only the nrComTapi component and set the DeviceIndex equal to -1 . then i added  the nrDeviceBox component and set the property  (nrcomm = nrcomTapi ) .

When i run this simple application in any PC which has no Modems it gave me only (Abstract Error : ) Message.

Can you remove all modems driver definition in your device and make this simple experiment and inform me about your result ?

Thanx in advance.

Hello

What nrComm version do you use?
What CBuilder version do you use?

Abstract error was in very old versions.
