Eloquence known problems and fixes
Linux platform

  This page documents known problems with Eloquence on the Linux platform which are either not related to code defects or have a low priority because an easy workaround is available.

Please note: This page is provided in the intention to be helpful to our customers. However the information is provided "AS IS" without any warranty.

Linux Platform

  • When using Telnet, pressing the BREAK key causes eloqcore to abort. This is related to a different behaviour of the Linux telnetd server.


    • In Reflection, you should choose the TELNET BREAK setting on the open connection dialog. This will avoid to kill eloqcore on Ctrl+Break - it will become the equivalent to ^Y.
    • In order to have a HALT/BREAK key, you can use the keyboard mapping function. Just send a NUL byte for a break. You can do this with the RCL function TRANSMIT "^(0)".
      For example: To assign the F12 key to break, open the keyboard map dialog, select the F12 key in the upper area, select "RCL Command" from the Combo-Box and enter the RCL command TRANSMIT "^(0)"
    • This works with HP-UX as well, so you can use a common setting.

  • Switching to 132 column mode is currently not supported on Linux console (error 880 is issued). This is a limitation of the Linux console driver which makes use of VGA hardware. (#526)

    The list of terminals which are capable to switch between 80/132 column mode is hard coded into eloqcore. Eloqcore returns error 880 when the terminal type not included in this list.

  • The Linux vt320 terminfo entry is not working correctly and has temporarily been removed from the distribution. If you encounter problems with an already installed version, you should remove the offending files from directory /opt/eloquence6/share/terminfo.

  • The keyboard sequences on the Linux console are not documented.
      ALT + H   - home display
      ALT + L   - lower end display
      ALT + D   - delete line
      ALT + I   - insert line
      ALT + J   - delete to end of screen
      ALT + K   - delete to end of line
      ALT + Tab - backtab
  • Linux console limitations:
    • Underline is simulated by colors on a color display
    • Dim ("half bright") is simulated by colors on a color display
    • Mixed enhancements don't mix as expected

  • The Linux curses library (ncurses) has problems with line drawing and enhancements on HP terminal types.

    A workaround for the Reflection/R1 terminal emulation is available. It provides a special terminal adaption to use the Reflection/R1 software in vt220 mode which is not affected by the curses problem.
