Hi, PPP does see the loss, the problem is that its totally wedged and cant do anything else. In the case where there is not too much data going across the serial line, the connection dropping has no adverse effect. I have LCP keep alives enbled and it does detect the link going away and does properly redial. However, it seems where there is too much outstanding data things get into trouble. Like I said, at this point I cant even kill -9 ppp. What more information can I provide to help track this problem down ? ---Mike
