来自「intercept tty is using for listening a U」· 代码 · 共 11 行

Review code for correctness, security, and efficiency.

Handle permissions on pseudo-tty's we create.

This should really be a simple, tty-specific program, with other
  programs (like tcpserver, netcat, or the shell) used to provide the
  more complex functionality.

Proper device locking, using whatever's appropriate according to local
  custom.
