The same thing was happening between my machine and my roommates new Amiga 3000. I switched the getty from ttya to ttyda, and the problem seems to have gone away. Oh, by the way, the getty I run on ttyda is also running at 38400 baud, and there haven't been any problems (I just had to add an entry to the gettytab file). -- Doug DeJulio ddj@zardoz.club.cc.cmu.edu
