The behavior you describe sounds like DESPR is periodically shutting down the thinwire segment due to collisions or jams. Note that the DESPR should be connected directly to the main ethernet thru an H4005 or equivalent transceiver with a heartbeat disable option. -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
