LAUNCHXL2-RM57L: Setting up serial communication via SCI4

Part Number: LAUNCHXL2-RM57L
Other Parts Discussed in Thread: HALCOGEN

I am trying to setup communication from SCI4 port. I have made necessary changes in Halcogen to initiate the port, but still I am not able to see any signal at the port. 

I have enabled the SCI4 driver.

I have selected SCI4RX & SCI4TX functionality in PINMUX tab.

Enabled SCI4 High interrupts on the VIM channel tab for both RX & TX.

Selected SCI functionality on SCI Port tab.

Selected RX interrupt tab on SCI global tab as well as enabled the SCI4 RX related notifications in my code. 

I am monitoring the signal at N2HET1[17] & N2HET1[19] pins as marked in below image.

Please let me know I am missing anything here.
