If your terminal has character + insert it will be used to shorten the delay. + +* Added the "termcap" .screenrc command to tweak your terminal's termcap + entry AND to customize the termcap generated for the virtual terminals. + See also the -L and -O command-line options, and the SCREENCAP environ- + ment variable. + +* Fixed screen's character handling when detached or suspended to NOT block + the child processes in their windows -- output continues to be processed + in the background. + +* Added a.k.a.s (window-name aliases) that allow you to customize the + window-information line, including being able to change the name on- + the-fly to reflect what's currently running in the window (see the + -k option, shellaka command, and ALSO KNOWN AS discussion in the doc). + +* Added the ability to log the output of a window to a file (see the + "C-a H" (log) command). + +* Flow-control can now be set for each window and switched interactively + (see the "flow" command, -f option, and FLOW CONTROL discussion). + +* Individual windows can be included or excluded from mention in the + /etc/utmp file (see the "login" command and -l option). + +* Added an activity monitor, which allows you to have a window watched for + the start of any output and alert you when it occurs (see the "C-a M" + (monitor) command). + +* Enhanced the information in the window-information line to keep track of + windows that have: logging turned on '(L)'; beeped in the background '!'; + became active while being monitored '@' (see the "C-a w" (windows) command). + +* Added an on-line help display that lists all the commands and their + key bindings (see the "C-a ?" (help) command). + +* Extended handling of the beep message (and also the new activity message) + to allow '~' to specify a literal beep (see the "beep" and "activity" + .screenrc commands). + +* You can now set the default action on receipt of a hangup signal: detach + or terminate (see the "autodetach" .screenrc command). + +* Routing of characters to their virtual terminals has been enhanced to + not drop characters nor (in rare circumstances) hang up screen. + +* The NFS compatibility has been enhanced. + +Major changes in version 2.0a: + +* Screen allows you to `detach' the "screen" session from the physical + terminal and resume it at a later point in time (possibly on a + different terminal or in a different login session). + + To get an impression of this functionality do the following: + + - call "screen" and create a couple of windows + - type Control-A Control-D (screen terminates; you are back + in the shell) + - call "screen -r" to resume the detached screen + +* Screen supports multiple character sets and the ISO 2022 control + functions to designate and switch between character sets. + This allows you, for instance, to make use of the VT100 graphics + character set or national character sets. |
