Some looking into telnet says that in regards to the CRLF setting, it will use only CR if that is what it receives, but if it gets an LF, it will use CRLF instead regardless of if there is a CR preceding. I am not sure if this has any impact on LAVA and it's ability to send commands in their entirety (as I have had issues with missing characters, out of order commands/characters, miss-timed commands, and others not covered by those).
