TCPSend() - Question about limits...

[JScript 71]

Hi,

Does anyone know say how many bytes TCPSend() can send at once?

I'll rephrase the question: How many packets are sent at one time?

$Socket = _TCPConnect($sCmpName, $iPort, 1000)
    If Not @error Then
        While $iSize
            $iSize = TCPSend($Socket, $vData)
            If @error Then ExitLoop
            $vData = BinaryMid($vData, $iSize + 1, $iSize)
        WEnd
        TCPCloseSocket($Socket)
    EndIf

João Carlos.

doono if there is one, maby max string len in autoit, but when you hit 'Error allocating memory', then your close

are you shure it send it all at once?

i dont think its up to autoit, its up to network and adapter, basicly (if im not wrong) it shud send one packet at the time and your speed and device is your limitation as for its max size, look at my edit:

http://en.wikipedia.org/wiki/Maximum_transmission_unit

Edit:

and from that page...

Large packets can occupy a slow link for some time, causing greater delays to following packets and increasing lag and minimum latency. For example, a 1500-byte packet, the largest allowed by Ethernet at the network layer (and hence over most of the Internet), ties up a 14.4k modem for about one second.
