Hexadecimal Reading does not match the reading of RealTerm Serial Capture

Question

Hi 
I am reading the output of a serial device that spits out hexadecimal  characters. When I read its serial output with the VISA read block (using a string display with HexDisplay option on) I am getting hexadecimal characters. However, when I read the output of the device with a serial data capture program, such as RealTerm, the  captured data does not match with the ones that I read in my string display in LabVIEW. I know for sure that RealTerm spits out the correct hexadecomal characters since these characters are the same as the ones I am expecting. ( I am actually looking for  some specific header characters that I don't seem to get when I read with LabVIEW).
Is there anyone out there who has an idea what the problem could be?
Thank you very much.

Hi;
Attached is the screenshot of RealTerm and the LabVIEW output. The hexadecimal character that I am  specifically looking for is 0X777F ( This indicates the beginning of the data whose format is 0x7FFF, 0x71DF, 0x0010, 0xFFF0, 0x0022, 0xFFA0, 0x0050, 0x0CCB, 0x0, 0x0, 0x0145). In the realterm screen shot, we can see  the characters 0XFF7F and the next 10 16-bits data words. Do you have any idea where I am making a mistake?
By the way, another question: I think 0XFF7F  reads as 777F.  is there any command that I can use in LabVIEW that allows me to read these as 777F right off the bat? 
Thank you very much for the response.
