8015

The file replication service cannot process the request. The system volume is busy with a previous request.


Do you have another app already using com2?

Try CLOSING the port before changing the Settings....

With MSComm1
  If .PortOpen Then
    .PortOpen=Fasle
    While .PortOpen
      DoEvents
    Wend
  End If
  .CommPort = 2
  .Settings = "9600,n,8,1"
  .InputLen=0
  .PortOpen=True
  While Not .PortOpen
    DoEvents
  Wend
End With
