Keyboard shortcuts

As Sellerie is often used like a terminal emulator, the shortcut keys are assigned to <ctrl><shift>, rather than just <ctrl>. This allows the user to send keystrokes of the form <ctrl>X and not have Sellerie intercept them.

  • <ctrl><shift>L -- Clear screen
  • <ctrl><shift>R -- Send file
  • <ctrl><shift>Q -- Quit
  • <ctrl><shift>S -- Configure port
  • <ctrl><shift>V -- Paste
  • <ctrl><shift>C -- Copy
  • <ctrl>B -- Send break

NOTES on RS485:

The RS485 flow control is a software user-space emulation and therefore may not work for all configurations (won't respond quickly enough). If this is the case for your setup, you will need to either use a dedicated RS232 to RS485 converter, or look for a kernel level driver. This is an inherent limitation to user space programs.


Sellerie has a few dependencies:

  • Gtk+3 (version 3.14 or higher)
  • vte 2.91 (version 0.44 or higher)

Once these dependencies are installed, most people should simply run:

meson build
ninja -C build

And to install:

ninja -C build install

If you wish to install Sellerie someplace other than the default directory, use:

meson build -Dprefix=/install/directory

for an unconfigured build or

meson config build -Dprefix=/install/directory

for an already existing build.

Then build and install as usual.

See INSTALL for more detailed build and install options.
