I don't have any information regarding an update for scannercast but I do have a few solutions to answer why scannercast is behaving this way.
Assuming you are using windows, open up device manager. This can be accomplished in Windows 7/Vista by right clicking on Computer, choose properties, and then choose Device manager on left. In Windows XP, right click on My Computer and choose properties, go to the hardware tab and click device manager.
Once in device manager, what shows up under Ports (COM & LPT)? If the com port here is not port 9 then Scannercast won't see it as 9.
Did you try restarting Scannercast? If a port is changed/updated a restart of Scannercast will be needed.
What makes you think it is on port 9 and not 8? Did you force it to be on port 9? Does port 8 work with Scannercast?
