Open Cash Drawer

This piece of code will pop open an MMF ED 2000 Cash Register. It sends the ascii value of A down com port 1. I put this code on planetsource code cause I had a hard time finding out how to do this. I tried the MSComm object and had a lot of difficulty with it. Hope this helps all the coders out there.

Sub popDrawer()

If hasCashDrawer Then
  Open "COM1" For Output Access Write As #1
    Print #1, Chr$(65); "A";
  Close #1
End If
Exit Sub
MsgBox ("Problems opening drawer")

End Sub
