The misc/screen-shm port
screen-4.0.3p9-shm – multi-screen window manager, with shm support for brltty (cvsweb github mirror)
Description
Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells). Each virtual terminal provides the functions of a DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g. insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows moving text regions between windows. This is a special version of screen patched to export the display via shared memory; it's for use with brltty.WWW: https://www.gnu.org/software/screen/
