I've managed to repeat this with the TRACE logging on. I don't want to post
the whole log out of security concerns for the server I'm connecting to, but
this is the section immediately after the `cli>` prompt comes in. Is this
showing the "shell" part that this test sends is actually being read back on
the input stream direct from the device? Not sure exactly how to read some of
this.
