If accessing other brokers, the complete urls should be formed like this: siteURL:port/basepath e.g mqtt.eclipseprojects.io:443/mqtt It is possible to have more than one connection to the same broker, for instance, using two different user/pass accounts simultaneously. To do this, add a connection id at the end of the broker: e.g mqtt.eclipseprojects.io:443/mqtt|1

If the third input is empty, reports the portion from the first position to the end of the string. If a position number is negative, counts from the end backward, so -1 is the last character, -2 is the next to last, etc.
