long RFGetLastError()
object.GetLastError() As Long
The state of the WireLess Studio link between the user application and the client.
Return value
One of this constants.
| WLNOERROR | The last operation was successful. All other codes are unrecoverable errors. |
| WLCOMMERROR | The last command was not sent to the RF terminal. |
| WLFUNCTIONFAILED | The response to the last command was not received from the RF terminal. |
| WLINVALIDRETURN | The response to the last command is improper. |
| WLNOTINITIALIZED | The connection is lost. After an error, subsequent calls to any WS function return this code. |

It is necessary to check the link state in all loops to properly close the
application if the link with the terminal is lost.
This method is available in all WS objects, and the error code is global (the
same) for all objects.

Public wsRfAuxPort As New RFAUXPORT
Public Sub Main()
Dim iRes As Long
