The wait state changes to ttyin. When I kill the getty >it changes to sciodtr and when I power the modem on/off it goes back to >sciodcd. Does it go to siodtr when you hang up? That is is the correct behaviour. It should stay in the siodtr state for a default of 3 seconds to give the modem a chance to see dtr drop. The default can be changed using comcontrol. If modem off/on is required to get out of the siodtr state then there is a software bug. > How can I get the getty to die after I hang up the phone? I thought that >'hc' in my gettytab would do the trick, but obviously it is not enough. You have to configure the modem to drop CD when the other end hangs up. Many modems can be configured to never drop carrier. This configuration is wrong for dialin lines and bidirectional lines. `hc' is for dropping DTR when the other end logs out. Bruce
