Prerequisites

Hardware
- A Linux based router/NAS/Plug Computer/Raspberry Pi/PC
- HID Keyboard
- 4D Systems OLED Display Graphics Module (serial port connection schematics) with Serial Platform PmmC or SPE (PICASO (9600 bps)/GOLDELOX) with the old 1-byte-per-command protocol
Software
- gcc 4.1.2 as buildroot trunk compiler (with libboost, gcc 3.4.6 and OpenWRT 7.09 I got defined in discarded section while linking, with gcc 4.2.4 and OpenWRT trunk can't resolve symbol '_Unwind_GetIPInfo' at runtime if an exception happens)
- libstdcpp_4.1.2 package
- libboost_program_options-gcc41-mt-1_34_1.so.1.34.1 and libboost_thread-gcc41-mt-1_34_1.so.1.34.1 from the Boost C++ library package from BTG
- ROTE package [Raspbian Stretch; sudo apt-get install libncurses-dev]
- SlugTerm and my modifications [sudo apt-get install subversion libboost1.62-dev libboost-program-options1.62.dev libboost-thread1.62-dev; rm Ftdi.cc; TIME_UTC_; Makefile]
- 4D.* (based on this)

I successfully ran it on OpenWRT 7.07-mipsel, Kubuntu 8.10-x86 and Raspbian Stretch-armv7l.
