Open
The Open function have two variants and may be called asynchonously or synchronously. Both variants result in an OpenResult but for the synchronous it is returned in the SyncRequestResult callback. The POIID in the login is essential and will decide whether the terminal needs the parameters or software. A POIID was supplied in the call to Start in a SaleApplInfo object, but may be changed when calling Open.
Before call to Open make sure to provide the ip address and port of the terminal.
