When you use VB, I assume you have a function something like this to find & open the
port:
--
Public Function FindTower()
On Error GoTo FindError
Dim strPort As String
Set Me.LEGOcom = New LEGOVPBrickLib.VPBrick
Me.LEGOcom.FindPort strPort
Me.LEGOcom.Open strPort
Me.LEGOcom.Monitor True
Exit Function
FindError:
If Err.Number = -520093436 Then
MsgBox "Tower not found"
Else
MsgBox "Error (" & Err.Number & ") " & Err.Description
End If
End Function
--
if you save the value of strPort, and execute .Findport again, it should return
another string, which is the name of the second port. Those are the values you use
when you open the port you want to communicate from.
Does that help? (is it clear?)
