However, there is no way to tell MacTCP that your link is slow and it should adjust it's timeouts. A better solution would be to interface with MacTCP directly. I suspect Apple has thought of this and probably has plans to address this in the future. Bottom line: I would not recommend spoofing with a fake .ENET driver unless the resulting network connection is ethernet speed or close (withing a order of magnitude) -brad
