+- 有些服务器连密码也不支持连着发送，则需要配置 `ExpectPassSleep`，默认为 `no`，可配置为 `each` 或 `enter`：
+
+  - 配置 `ExpectPassSleep each` 则每输入一个字符就 sleep 一小段时间，默认 100 毫秒，可配置 `ExpectSleepMS` 进行调整。
+  - 配置 `ExpectPassSleep enter` 则只是在发送 `\r` 回车之前 sleep 一小段时间，默认 100 毫秒，可配置 `ExpectSleepMS` 进行调整。
+
 - 如果不知道 `ExpectPattern2` 如何配置，可以先将 `ExpectCount` 配置为 `2`，然后使用 `tssh --debug` 登录，就会看到 `expect` 捕获到的输出，可以直接复制输出的最后部分来配置 `ExpectPattern2`。把 `2` 换成其他任意的数字也适用。

+- Some servers may not support sending password continuously. Then you need to configure `ExpectPassSleep`, which is `no` by default, and can be configured as `each` or `enter`:
+
+  - Configuring `ExpectPassSleep each` will sleep for a short period of time for each character send, the default is 100 milliseconds, and you can configure `ExpectSleepMS` to adjust it.
+  - Configuring `ExpectPassSleep enter` will only sleep for a short period of time before `\r` send, the default is 100 milliseconds, and you can configure `ExpectSleepMS` to adjust it.
+
 - If you don’t know how to configure `ExpectPattern2`, you can first configure `ExpectCount` to `2`, then use `tssh --debug` to log in, you will see the output captured by `expect`, and you can directly copy the last part of the output to configure `ExpectPattern2`. Replacing `2` with any other number will also work.
