Write_Bare_Ctrl_C
SSHLibrary.Write_Bare ${ctrl_d}
Flush_Read
- [Arguments] ${delay}=1
[Documentation] Attempt to read excess data (probably just multiple prompts), ignoring failure.
... Log the data or error message. Return None.
... \${delay} parameter tunes how long a period of inactivity has to be to consider all excess data to be read.
+ [Arguments] ${delay}=1

Flush_Read
- [Return] ${text}
+ RETURN ${text}
RemoteBash__Wait_Iteration
[Documentation] Send a newline and wait for prompt. On success, return the text before the prompt.
... The newline is there to avoid disconnection due to idling.
SSHLibrary.Write ${EMPTY}
${text} = SSHLibrary.Read_Until_Prompt
- [Return] ${text}
+ RETURN ${text}
Wait_Without_Idle
- [Arguments] ${timeout} ${refresh}=1s

Invoke_With_Timeout
- [Arguments] ${command} ${timeout}
[Documentation] Enter ${command}, wait until it finishes and return the output.
... If it does not finish within timeout, abort it and fail.
... In either case, flush read.

[Documentation] Log text gathered by SSHLibrary.Read_Until_Prompt.
[Documentation] Try to read SSH to see prompt, but expect to see no prompt within SSHLibrary's timeout.
... Log any text seen, to help debug what happened when the tool exited early.
