16.2 Write out the window’s termcap entry

Command: dumptermcap

(C-a .)
Write the termcap entry for the virtual terminal optimized for the currently active window to the file .termcap in the user’s $HOME/.screen directory (or wherever screen stores its sockets. see Files). This termcap entry is identical to the value of the environment variable $TERMCAP that is set up by screen for each window. For terminfo based systems you will need to run a converter like captoinfo and then compile the entry with tic.
