As part of installing our Ungermann-Bass NET/ONE, I have noticed that the VAX usually doesn't drop DTR on logout. Since we use the DTR signal to the NET/ONE to enable and disable connections, this is inconvenient. In looking at the sources for the DZ driver, I noticed a line in dzopen that set was commented out which set the hangup- on-last-close bit in the tty structure. Also looking at the source for getty.c, I noticed that the old HUP bit has gone away, so you can't set up alternate entries for /etc/ttys that will do the trick. I can either change the DZ driver by un-commenting that line, or add a line to getty.c to set the hangup bit. I would like to have this work for all lines; not just those available for logons. Question: Does anyone have a reason why this mode should not be the default? Can anyone comment on the 4.2bsd handling of modem control in general? - Alan S.
