@@KeithB, there is no SoftwareSerial support for the MSP432. You can however use Serial1.xyz() just as you do with Serial. Serial1's TX is located on pin 4 and RX on pin3.
Please see the pinmap posted here: http://energia.nu/pin-maps/guide_msp432p401r/
Note that baudrates lower than 9600 are currently not supported for the MSP432.
