[RESOLVED] exception "CTL_E_GETNOTSUPPORTED"

HI,
I am trying to dial a computer from another computer using Modem for sending files and messge.Follwoing is the code done in dialing computer

Code:

---

Text1.Text = "Test string from App1 "
        Number$ = InputBox$("Enter phone number:", "Number$")
        If Number$ = "" Then Exit Sub
        Temp$ = Status
          Status = "Dialing - " + Number$
        DialString$ = "ATDT" + Number$ + ";" + vbCr

        On Error Resume Next
        If MSComm1.PortOpen = False Then
            MSComm1.CommPort = 4
            MSComm1.Settings = "9600,N,8,1"
            MSComm1.PortOpen = True
            MSComm1.RThreshold = 1
            MSComm1.RTSEnable = True
            MSComm1.SThreshold = 1
            'MSComm1.Handshaking = MSCommLib.HandshakeConstants.comRTS
        End If

        MSComm1.Output = DialString$
        Do
   
            Temp$ = Temp$ & MSComm1.Input
                      If InStr(Temp$, "NO DIALTONE" & vbCrLf) Then
                End
            End If
        Loop Until InStr(Temp$, "OK" & vbCrLf)

                  MSComm1.Output = Text1.Text

---

But after the dial tone, i am getting the exception "CTL_E_GETNOTSUPPORTED " at the line MSComm1.Output = Text1.Text Can you please tell me what may be reason for this .

The error says that the GET operation is not supported so presumably the underlying COM object doesn't support getting the Output property value or something that it depends on.

But how this is happened in the given code. Any reason which will help me to find out the reason

I'm not familiar with the COM component your using but, regardless, I just realised that you're setting Output, not getting it. I have to say that I really don't know what the issue is but it's just another reason not to use COM, if you can avoid it.

What else i can use instead of COMM for data transfer between computers using a dial up modem ?

Sockets maybe?

:check:
The error was with the inital setting of the port.
By modifying the same, i am able to do the data transfer
