Winsock Data Arrival event trigger just once

Question

See more:

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.

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

Please advise.

Thanks

What do you expect to happen after the line:

VB

sockP.SendData sText

in the above code?

sTest are commands sent to the terminal.
Suppose sText is ATE0 then in telnet i am getting ATE0 and then OK.

sockP_DataArrival is triggered once and i get back "ATE0" but not OK.

I tried different commands where i expect more then 1 reply for a command but i am getting databack just once from the terminal.

My comment was directed at the logic of your code. After that command you fall through into the Sub - how does this work?

Ok problem is solved. It was me who was making mistake while passing command which i didnt mentioned in this post.

I was just missing new line character while sending commands.

Thanks for posting comments for helping me out.
