- Hardware
- A Linux based router/NAS/Plug Computer/PC with USB ports (e.g. Asus WL-500g Premium)
- USB keyboard (e.g. Keysonic ACK-3400 U)
- DisplayLink device (e.g. Samsung U70)
- Software
- Binaries (extract to /)
- Building for OpenWRT
- gcc 4.1.2 as 8.09 compiler (with libboost, gcc 3.4.6 and 7.09 I got defined in discarded section while linking, with gcc 4.2.4 and trunk can't resolve symbol '_Unwind_GetIPInfo' at runtime if an exception happens; the SVN trunk package gave some compile error, too.)
- packages: libstdcpp_4.1.2 (brcm*), libusb, libfreetype
- modules: 2.4: input.o, evdev.o, hid.o; 2.6: input-core.ko, evdev.ko, usbhid.ko (for brcm-2.4 a patch is necessary, but even then hid.o doesn't get built for me.)
- libboost_program_options-gcc41-mt-1_34_1.so.1.34.1, libboost_thread-gcc41-mt-1_34_1.so.1.34.1 from the Boost C++ library package from BTG
- ROTE-256
- SlugTerm and my modifications (based on tubecable; 26C3: Reverse-Engineering DisplayLink devices)
- font: I recommend FNTs (FON2FNT). BDFs. PCFs don't have line drawing characters and are slow; no cache yet. Scalable fonts are not layed out correctly yet.
