Author: marcel Date: Sun Mar 9 21:06:22 2014 New Revision: 262957 URL: http://svnweb.freebsd.org/changeset/base/262957 Log: Change the terminal type/class for enabled serial lines to 3wire. This allows us to change the uart(4) driver to not hardcode specific line settings for the serial console. A terminal type of 3wire makes sure the console still works when no DCD signal is present, which preserves behviour. When it is known that the terminal server (or DCE in general) provides DCD, a terminal type/class of std can be used. This has the effect of being logged out when one disconnects from the console -- improving security overall. Likewise, when uart(4) does not fixate the baudrate, one can change the terminal type/class to set a specific baudrate. An operator can use this to change the console speed mid-flight, without needing a reboot. Of course it helps in this respect if and when the firmware can be configured from the OS. The above mentioned capabilities depend on uart(4) being changed, which is to happen next.
