There's nothing built-in at the moment, but there is a bit of JS code that can handle 9600 baud-ish on the software serial issue that's on GitHub: https://github.com/espruino/Espruino/issues/549
Realistically it's not that quick at the moment. When there's something as part of the firmware it should be able to handle pretty decent numbers of serial ports.
