Problems with serial communication LAUNCHXL_f28379D

Hi.

I want to use LAUNCHXL_f28379D to communicate with other microprocessor via serial port, so I'm doing some tests and I can't do what I need.

The objective is to use the launchpad to send an specific frame of 8 bytes with a period of a second using SCI_C, to test the proper working I have done a simulink program where the launchpad sends "1 10 2 10 3 10 4 10 5 10" frame (unit 8, with no package header or terminator) and I have connected SCI_C to my PC's USB using an FTDI adapter to monitor what is sending using an specific software. What I receive is this: 06 00 98 80 18 00 98 80 1E 00 98 80 60 00 98 80 (Hex) or ..˜€..˜€..˜€`.˜€ characters.

As you can see the data that I receive isnt 8 bytes and the numbers doesnt coincide.

I will appreciate any help, thanks in advance!

EDIT: I have also tryed to do sending only a number and these are the results:

If I send a "49" (Uint 8) what i receive is "06 0f" (supposedly in hexadecimal)

If I send a "2" (Uint 8) what i receive is "18 00" (supposedly in hexadecimal)

Thanks again!

FInally I solved the problem adjusting the "oscillator clock (OSCCLK) frecuency" to 10Mhz in CPU 1 configuration.
