**Parameters**

hObject

\[in] Handle which specifies the driver object created by [OpenNeoDevice](https://docs.intrepidcs.com/neovi-api/win32-api-overview-intrepidcs-api/basic-functions-overview-intrepidcs-api/openneodevice-method-intrepidcs-api)

iPort

\[in] specifies the TCP/IP Port where the server will be established.

If the server was started successfully the return value will be non-zero.

**Remarks**

This method creates a TCP/IP server in the DLL. This server can be attached to by any TCP/IP clients using the RAW API or using the DLL by specifying TCP/IP with [OpenNeoDevice](https://docs.intrepidcs.com/neovi-api/win32-api-overview-intrepidcs-api/basic-functions-overview-intrepidcs-api/openneodevice-method-intrepidcs-api). Only one server is allowed at a time.
