identify the gap between data coming from visa

Hi..

 

I have an instrument that would continuously send out 56 bytes of data for every 0.5ms at 2000000baud rate ,that is  connected to serial port of a NI PXI box. I want to extract all 56 bytes from every transmission continuously.
After sending 56 bytes,a gap of 220microseconds will occur to complete 0.5ms(which means one complete transmission of data).

So the problems is to identify  how to find that gap coz ,our port would start reading the bytes any palce.

Plz Help me out.

 

Thanks in advance.
