in rare cases, serial initial reads/writes may be lost

[dave russo]

In rare cases serial reads/writes may be lost at startup due to typo bug: in serial.js serialDispatch() the line:

serialport.isOpen ?

should be

serialport.isOpen() ?

Since isOpen is a function, the test is always true, even if the serial port isn't really open. As a result, serialDispatch() never queues reads/writes
