File transfer of larger size through serial port

[Technical_details]

Hi

I need to transfer files of larger size may be around 20Kb through serial port. Can some one suggest some idea or can provide any sample VI for achieving this. i guess we cannot send the complete file at a stretch, so we may need to form some packets and then send. If i am right i need some help for achieving this.

Hello,

I have attached the VI to try.

You may want to use something like the XMODEM protocol. 

I believe you can find a version of XMODEM that can be used with an NI-VISA session located here on the OpenG forums.
