It does.
7 char Virtual console capture devices
0 = /dev/vcs Current vc text contents
1 = /dev/vcs1 tty1 text contents
...
63 = /dev/vcs63 tty63 text contents
128 = /dev/vcsa Current vc text/attribute contents
129 = /dev/vcsa1 tty1 text/attribute contents
...
191 = /dev/vcsa63 tty63 text/attribute contents
NOTE: These devices permit both read and write access.
Andreas.
