What to do when connections seem to hang

At times cu requests seem to take a very long time. While you are waiting for a cu request to complete, consider the following:

the connection server waits 45 seconds for each chat script timeout
constructions such as
```
in:--in:--in:
```
in chat scripts cause the connection server to wait for three 45-second timeouts
on failure, the connection server typically retries the entire transmission

Given this, you could easily see five minutes go by before a cu request reports an error. If this occurs, you can use the connection server in debug mode so you can see where the timeouts are going and why it is taking so long. See ``Using the connection server in debug mode'' for more information.

Using cu -v can also provide an indication of what is happening.
