I have a program that captures data out of the comm port. I also can TELNET to the device  but when I try and invoke the peekData or GetData It see's nothing. I am using another form to display the data back, Could that be the issue? Here is the code out of the books online of the GetData I am using. Is there any good examples of TCP/IP (telnet)programs out there?
 
Private Sub Winsock1_DataArrival_(ByVal bytesTotal As Long)
    Dim strData As String
    Winsock1.GetData strData
    Text1.Text = strData
End Sub

Here is how it is being called.

Private Sub mnuTelnetOpen_Click()
   
   'Winsock1.RemoteHost = "140.248.152.196"
    Winsock1.RemotePort = 23
    'txtTerm.Text = ""
    Winsock1.Connect
    TCPform.Show vbModal
End Sub

Private Sub Winsock1_Connect()
 Dim PauseTime, Start, Finish, TotalTime
 Dim error1, last1
 
    Winsock1.SendData "root" & Chr(13)
    Beep
    Winsock1.SendData Chr(13)
    Winsock1.SendData Chr(13)
    'MSComm1.InputLen = 0 ' Get all available data
    'MSComm1.Handshaking = 1
     
   
       
     If MSComm1.PortOpen = True Then
     
        Winsock1.SendData "ls" & Chr(13)

Thanks in advance for your help.

smurray,

When you open a form modally, you stop all processing on the calling form until you return from the modal form.  Therefore, you are not getting your events.  You need to not show the form modally, and some how create a "pseudo-modal" form.  By that I  mean, it's operates like a modal form, but is not really modal.

Thanks for the tip on the modalm but I still cannot read back from the device. Is there an example on how to GetData during a Telnet session?

what you did looks perfect   I have a telnet OCX of my own, and that's how I made it.
