I've seen the same symptoms on: * A Sun-3/50 running SunOS 4.1.1_U1, using ttyb; * A Sun Ultra 2 running (IIRC) Solaris 2.5, using an Aurora multi-port S-Bus card; * A Sun Ultra 10, using an Aurora multi-port PCI card. The Suns were using Aurora drivers. I was never able to get one of those systems' ttya or ttyb (using Sun drivers, of course) to hang that way.help
