In this way broadcast can work the same as sending regular packets. -Mark Rosenstein work: mar@proteon.arpa (617) 655-3340 other: mar@borax.lcs.mit.edu (617) 497-4863 ...ihnp4!mit-eddie!mar Disclaimer: I do work for Proteon, but as a programmer not a hardware person. I think I've just told the truth, although this is not an official statement of Proteon, Inc.
