Re: How to let dial-connection use my virtual port?

If your virtual driver is exposed as a serial port, you will need manually
install a modem (through telephon.cpl) on the virtual com port.

Good luck!

Brad Williamson:
thanks for your answer
I have done what you tell me.
But, The when Telephon.cpl enum all serial ports.
After it open my virtual port, It send ioctl code ---0x002b002c,
I think it is FILE_DEVICE_MODEM code, not belong to serials ioctl code,
SO i implement this code,
after this, it close the handle,The telephon.cpl does recognize my port.
Why, I need deal with "0x2b002c",How to finish the code?
Thanks
Jerry.
