| XTerm | ✅ | ? |❌ |`TERM=xterm+256color2` `COLORTERM=24bit` | See note about DirectColor. Must configure with `--enable-direct-color`. `TERM=xterm-direct` seems to have the undesirable effect of mapping low RGB values to a palette; I don't yet understand this well. The problem is not seen with the specified configuration. Sixel support when built with `--enable-sixel-graphics` and run in vt340 mode. |
