So lnc resets might be causing the silo overflows, but it seems that something about ppp or sio is causing the lnc resets. I hope there will be a fix for this. It takes over my console screen, and I'd be quite worried if and when I have to run this machine as a gateway through ppp. Terry _____________________ I n D i G o Terry Lee _____________________ Technical Director i n t e r n e t 745 Stanford Avenue _____________________ Palo Alto, California 94306 d e s i g n 415 424 0747 _____________________ terryl@cs.stanford.edu g r o u p http://www.mall.net/terry _____________________ http://www.mall.net Professional World Wide Web Consultants
