Problem With Tcpip

[Tam0r 2]

hi.

I've written a server module which checks if clients are connected. If connecting via hyperterminal and sending 2 the server shows the client online. Usually when closing the connection properly the client sends 1 to the server, so the server knows the client is offline. But if the connection is terminated for some reason (e.g. internet connection is lost) the client can't logoff from the server and the server shows this client online, although it is not.

I've tried to fix this problem with this code:

elseif $err[$i] <> 0 Then
        $ConnectedSocket[$i] = -1
        if $user = 0 Then
            Else
        $user = $user -1
    $Client[$i] = "0"
    $iptext[$i] = "000.000.000.000" 
    $err[$i] = "0"

Is there something wrong with the code, or is there a better (operative) way to say the server, that the client is offline?

Here's the programs INI followed by the program itself. Sorry for the grubby code, its still in the developing phase.

(You can use one of this ports, if you want to try it with the hyperterminal)
