When we starting using XENIX, our communication program started catching signals 1 (SIGHUP - hangup) and 2 (SIGINT - interrupt). We developed the simple communication program by opening the device file and using ioctl. We communicate using Digiboard PCxE cards through local serial connections and by using modems. Does anyone know what causes these signals. Can at least signal 1 be safely ignored? Thanks, Tim Mikula (mikula@cs.umn.edu)
