Question

determine the status when using MSCOMM32 ocx to open/close a drawer

Asked by: Priya25

Hello All,
I'm using  MSCOMM32 ocx to be able to open a drawer.Refer to my Code..
Everything works fine.
But now I'm trying to display a message like
"Drawer is already open"
when trying to open the drawer when it is already open...
The drawer can be opened only by my application, and it is being closed manually..
When closed, nothing changes in the status of the port...that is why I'm not being able to check for the status if it is open or closed.
One solution is to close the drawer by the application itself and set a global variable as the status of the drawer...but this not being accepted by my users since according to them.
Its a bit complicated here I know...But does anyone have any idea how can I achieve this..

Private Sub Command1_Click()
    Dim output(5) As Byte
    output(1) = 27
    output(2) = 112
    output(3) = 0
    output(4) = 50
    output(5) = 250
    MSComm1.output = output
    End Sub

Private Sub Form_Load()
   ' Use COM1.
   MSComm1.CommPort = 1
   ' 9600 baud, no parity, 8 data, and 1 stop bit.
   MSComm1.Settings = "9600,N,8,1"
   ' Tell the control to read entire buffer when Input
   ' is used.
   MSComm1.InputLen = 0
   ' Open the port.
   MSComm1.PortOpen = True
   End Sub

Private Sub Form_Unload(Cancel As Integer)
   ' Close the serial port.
   MSComm1.PortOpen = False
End Sub

Regards,
Priya

What type of draw is it?  Some draws you can enquire on the draw status.

PS in your code do you have option base 1?
If you don't.....
Dim output(1 To 5) As Byte ' is better

   Dim FrFile As Integer
   FrFile = FreeFile
   Open "LPT1" For Binary Shared As #FrFile
   Put #FrFile, , output

End Sub


But we are still not able to enquire about the status...
I'm reading the values of the bits of the port when the drawer is open and when closed, but there is no bit which is being changed with the drawerbeing closed or opened!!!
Please help,
Priya

Epson support is quite good, if you can't find what you want above, why not call Epson, they are normally very helpfull.
