svn commit: r197481 - head/sys/teken

[Ed Schouten]

New Revision: 197481
URL: http://svn.freebsd.org/changeset/base/197481

Log:
  Add a new escape sequence to switch between cons25 and xterm.
  
  Just run this to switch to xterm:
  
  	printf '\e[=T'
  
  If you get bored and want to switch back to cons25, run this:
  
  	printf '\e[=1T'
  
  I can now send an email to the lists, asking whether people are
  interested in trying the xterm emulator.
