Author: bde Date: Thu Feb 21 08:37:39 2019 New Revision: 344427 URL: https://svnweb.freebsd.org/changeset/base/344427 Log: Restore syscons' terminal emulators. The trivial fixes to make them compile will be committed later. The "sc" emulator has the advantages of full support for cons25 and running about 8 times faster than teken (for writing to the frame buffer). The "dumb" emulator has the advantage of being simple. Runtime choice of the emulator is good, but compile time choice is bad.
