If you're already familiar with NetBSD, this information may not be particulary new or useful to you. It's not particularly Atari-specific. I do however use this for my own reference when I install NetBSD/atari.

Compiling programs on the Atari can take days (or weeks!). Screen allows you to regain control of a disconnected session if your terminal connection disconnects for whatever reason.

  1. Make sure to run through the pkgsrc configuration described in the packages section.
  2. cd /usr/pkgsrc/misc/screen
  3. sudo make PKG_OPTIONS.screen="ncurses" install
  4. cp /usr/pkg/share/examples/screen/screenrc ~/.screenrc


Notes:

  • It seems pretty logical to include ncurses support per above, though I'm not sure to what extent this is really necessary.
  • The screenrc example seems to have better, more reasonable defaults than the /etc example.
  • The screen user's manual is here.
    • screen -ls allows you to view what screen sessions are currently active.
    • screen -R reconnects to a disconnected session, creating a new session if one doesn't already exist.
    • screen -x connects to an existing session (multi-display mode).
    • Once you're in screen, the following escape sequences are handy:
      • Create a new window: Ctrl-A c
      • Switch to a different window via a menu: Ctrl-A "
      • Toggle to the next window: Ctrl-A <space>
      • Create a new region: Ctrl-A S
      • Toggle to the next region: Ctrl-A <tab>
      • Detach from screen: Ctrl-A d
      • Enter scrollback mode: Ctrl-A [
        • Use arrows, page-up / page-down to move around, Esc when done.
        • Scrollback mode is necessary as once screen is running, scrolling in your terminal program won't be functional.
        • With the default .screenrc the scrollback buffer is set to 1000 lines.
