```
control.ControlMode.send(self, command: Command) -> Result<BlockResult, Error>
```

Send one command and wait for its result block.

# Errors

Returns an error when the command cannot be written as a control-mode
line, the connection has closed, or its deadline elapses while queued,
being written, or awaiting a response.

# Cancel safety

As for [`ControlSender::send`]: a command dropped while queued is never
written, and one already committed may run.
