If a terminal-tty disappears, it should be handled like a HUP would be, analytically it is the exact same situation as a carrier drop on a modem. The implementation may need to do tricky stuff, but the result should be exactly like a HUP seen from userland. If a comms-tty disappears, it should be handled like any other disappearing device: ENXIO. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
