First, run hidusb-relay-cmd-setup on the device its connected to. Then run libremanage for usage and documentation. For FSF, also seen gluestick page on beaglebone. Background: GNUtoo has been working on a similar setup. see https://wiki.parabola.nu/Standalone_BMC. fsf sysadmins, see rt 1346340 for further development ideas. Ian Kelling also has a package for openwrt, not yet published. Ask him if you are interested. libremanage-color and libremanage-serial were for dealing with console issues in coreboot. However, most or all of the problems they solved were due to alyssa's mistake of trying to make it work over an "ssh command" which was not connected to a terminal. Simply sshing, then doing screen /dev/ttyUSB0 115200, etc might fix all that. Once I test that out, I will remove these files.
