Hi TiBlay

It works on my pc. Try the code below instead but this will only show free ports. You will also need the Microsoft Comm Control.

Private Sub Command2_Click() On Error Resume Next ' IN CASE OF INVALID PORTS     For i = 1 To 16              MSComm1.CommPort = i                  MSComm1.PortOpen = True                  If MSComm1.PortOpen = True Then             MsgBox "COM" & i & " OK", vbInformation             MSComm1.PortOpen = False         Else             MsgBox "COM" & i & " Not OK", vbExclamation         End If              Next i End Sub
