    Winsock DataArrival event just triggers once

    When i send a command to a terminal, there are chances that more than more reply are sent.
    Winsock_DataArrival Triggers just once when first reply is sent. Its is not triggering when second reply is sent by the terminal.
    I telnet to the terminal and can see multiple replies coming through.

    With sockP

    If .State <> sckClosed Then
    .Close
    End If

    .Protocol = sckTCPProtocol
    .Connect sIPAddress, sIPPort

    Do
    DoEvents
    Loop Until .State = sckConnected Or .State = sckClosed

    sockP.SendData sText

    Private Sub sockP_DataArrival(ByVal bytesTotal As Long)

    Dim rData As String
    rData = ""

    sockP.GetData rData, vbString
    txtReplies.text = rData
    DoEvents

    End Sub

    DataArrival is event is just being triggered once. I dont know what am i doing wrong.
    Ex: If i send ATE0 .. i get back just ATE0 and not OK which is followed.

    I am not much familiar with winsock in vb6 and i cant upgrade to .net at this point.

    Please advise.

    Thanks

    Why not use remote desktop? Or the command-line equivalent to connect to a modem

    I think it can create problem with Windows Vista and Windows 7.
    Also this should make sure that telnet service is installed on every machine using this.

    Glad you go it fixed, I was about to suggest something to that effect. I have been using the Winsock control in a commmerical program I created for over 10 years now and never had an issue with it.
