Comm port open or closed?

How can you check the status of a comm port if it is open or closed? I thought comm1.portopen would return the status, but its not. It always returns false. The simpliest way, I just want to know if the comm port is in use or not.
Thanks..

The PortOpen property should return the port status. e.g.

If MSComm1.PortOpen = True Then
MsgBox "Port is Open"
Else
MsgBox "Port is Closed"
End If

If that still doesn't work, try and open the comm port. If it is already open, it produces a trappable error, e.g.

On Error GoTo OhDear

MSComm1.PortOpen = True

Exit Sub

OhDear:
If Err.Number = 8005 Then
MsgBox "Port is already open!"
Else
MsgBox Err.Description
End If

Hope that helps,
