I was a little >disappointed. Does anyone know just what it will catch? When you kermit BYE in vt100 2.8 before doing a transfer, vt100 constructs a packet using a pointer which never had memory allocated for it...i.e. it points to NULL, so Kermit happily scribbles all over low memory. I think it scribbles over less than 100 bytes, so memwatch might catch it. Beyond that, you nuke the autovector interrupts and there's not much hope of getting out intact. I sent fixes for this (and several other bugs) to Tony, so this should disappear in 2.9, and you'll have to find a new `favorite guru'. -dan riley (dsr@lns61.tn.cornell.edu, dsr@crnlns.bitnet) -wilson lab, cornell u.
