Until SMS credentials are configured SMS interface is active only for first 10 minutes after power-on and uses following format:

Q1234567890123456 - device UID
COMMAND - issued command
RETVAL - OK / ERROR / value(s) returned by the issued COMMAND

For those commands which return multiple values the RETVAL format is:
