LAYERS (l) LAYERS (l) command relogin(lM) when the first layer is created. relogin(lM) will reassign that layer as the user's logged-in terminal. An alternative layer can be designated by using relogin(lM) directly. layers will restore the original assignment on termination. Layers are created, deleted, reshaped, and otherwise manipulated in a terminal-dependent manner. For instance, the AT&T Teletype 5620 DMD terminal provides a mouse-activated pop-up menu of layer operations. � , The method of ending a layers session is also defmed by the terminal. If a user wishes to take advantage of a terminal-specific application software package, the environment variable DMD should be set to the pathname of the directory where the package was installed. Otherwise DMD should not be set. EXAMPLE layers -f startup NOTES where startup contains 8 8 700 200 date ; pwd ; exec $SHELL 8 300 780 850 exec $SHELL The xt(7) driver supports an alternate data transmission scheme known as ENCODING MODE. This mode makes layers operation possible even over data links which intercept control characters or do not transmit 8-bit characters. ENCODING MODE is selected either by setting a configuration option on your windowing terminal or by setting the environment variable DMDLOAD to the value hex before running layers: export DMDLOAD ; DMDLOAD=hex If, after executing layers -f file, the terminal does not respond in one or more of the layers, often the last command in the command-list for that layer did not invoke a shell. WARNING To access this version of layers, make sure /usrlbin appears before any other directory, such as $DMD!bin, you have in your path that contains a layers program. (For information about defming the shell environmental variable PATH in your .profile, see profile(4)) Otherwise, if there is a terminal-dependent version of layers, you may get it instead of the correct one. FILES When invoking layers with the -s, -t, -d, or -p options, it is best to redirect standard error to another file to save the statistics and tracing output (e.g., layers -s 2>stats); otherwise all or some of the output may be lost /dev/xt??[0-7] /usr/lib/layersys/lsys.B ;7 ;3 $DMD/libllayersys/lsys.8 ;?;? -2-
