Introduction +2. Is dotscreen different as screen? +3. Installation instructions +4. Functions description +5. Further development + + +1. Introduction +=============== + +Dotscreen, is a system which allow a person direct access to unix via +a braille display. The emphasis is on direct, because the braille +display is connected directly to the serial port on the unix +machine. You no longer must use a dos machine running a terminal +emulation logged into a unix machine. Dotscreen is built on top of +screen, a powerful full-screen window manager for unix tty terminals. +Screen keeps track of what is being displayed in each window that it +is managing so that it can easily switch back and forth between these +windows. Dotscreen makes this stored window information available via +a braille display. Dotscreen only allows access to tty terminal +sessions, it does not allow access to X-Windows, however, it will run +in an xterm window. Currently, it works with the TSI Navigator 40 and +the TSI PowerBraille 40 braille displays. We plan to support other +displays as demand and information about other displays is made +available to us + +2. Is dotscreen different than screen? +====================================== + +All of screens functions still work in dotscreen. A few of the +functions are not accessible via braille, but we expect to remedy that +in future releases. + +3. Installation instructions +============================ + +Please read the INSTALL file for full installation instructions. +In addition to those instructions, note that you must create +a .screenrc file and that file must contain the type of braille +display that you are using and the serial device that the display +is connected to. A minimal .screenrc file should contain something +like the following four lines, (these are only examples, please +customize them for your configuration) + + +# example of .screenrc when using braille display +bd_start_braille on +bd_type powerbraille_40 +bd_port /dev/ttyS0 +bd_braille_table /home/gardner/us-braille.tbl +# end of example + + +4. Functions description +======================== + +The basic operation of screen is described in README. The braille +navigation commands are similar to commands usually found on dos +braille screenreaders. Also, because dotscreen is built on top of +screen, the user can switch back and forth easily between many running +applications. The braille commands can be changed any time after +starting screen using the internal screen "C-a :" command line. All +braille commands begin with "bd_"; following is the list of braille +commands: + +bd_start_braille on/off # Starts/stops using braille features on screen +bd_link on/off # links/unlinks braille cursor to/from screen cursor +bd_bell on/off # turn on/off sending bell-signal to terminal +bd_scroll on/off # enables/disables scrolling +bd_skip on/off # skip/don't skip balnk lines +bd_width <integer-value> # number of braille cells that user want to use, + # this value is always <= total number of cells +bd_ncrc <interger-value> # number of cells displayed on the right side + # of physical cursor (default = 1) +bd_info <integer-value> # displays braille/screen cursor position + # depending on its value, (no info: 0, only + # bc-info: 1, only sc-info: 2, bc- and sc-info: 3 +bd_port <serial-device> # serial port which braille display is connected to +bd_braille_table <bl-table> # braille table to be used. German, US and GS + # braille tables are provided +bd_type <braille-display-type> + # braille display type being used + +Note: currently valid value for some parameters: +bd_type: + 1. navigator_40 + 2. powerbraille_40. + +bd_braille_table: + 1. gr-braille.tbl German braille code + 2. us-braille.tbl US computer braille code + 3. gs-braille.tbl GS braille code + +Since the braille tables are in files, you should give the full +pathnames of the files either in .screenrc or using the +internal screen "C-a :" command line. + +5. Further development +====================== + +As mentioned above, currently Dotscreen works with Telesensory braille +displays the PowerBraille and the Navigator because Telesensory has +given us the information needed to program their braille display. We +plan to add support for other braille displays when and if we get the +requisite information from the braille display manufacturer. +Also some things such as cursor navigation from the braille display +have not been implemented. If you find a feature missing that +you wish to have, please contact us. + +This software has been developed within the Science Access Project at +Oregon State University under the direction of John Gardner. + +Authors: Hadi Bargi Rangin (bargi@dots.physics.orst.edu) + Bill Barry (barryb@dots.physics.orst.edu) + |
