 When `0x12` (DC2) is received in tty-resizer, subsequent chars are captured in tty-resizer, and they will not propagate to real TTY. `t` is terminator, then capture mode in tty-resizer is finished, and subsequent chars are propagated to real TTY, and `TIOCSWINSZ` ioctl would be issued to the specified TTY. `c` means "cancel" for tty-resizer, then capture mode will be finished, and happens nothing.
 
 0-9 and `;`, `t`, `c` is valid chars on capture mode. Capture mode will be aborted when other char is received - it would be treated as `c`.

-TTY Resizer might not work fine with full-screen application like Vim. Noisy chars (for Vim) might be input, and TTY Resizer might not be able to set resized console size while that app is running.
