Send a file to a PIC

[Ron Marcus]

I know it remind me something here... check RealTerm
http://realterm.sourceforge.net/

I tried this link but it would not work for my PC. From a little research it looks like XMODEM is the way to send a file with Hyperterminal but there needs to be some sort of checksum routine on the PIC side. Does anyone have further info on this?
Thanks,
Ron
