I can write this file if I know the commands and formats for windows command prompt to open the com port and send decimal or hexadecimal formatted bytes.

According to : http://www.virtualblueness.net/asem51/bbatch.htm

Open the Com Port (adjust com port settings as needed):

MODE COMX:9600,N,8,1,P

Wait a little bit

SLEEP 9600

%1 is a paramater, i.e your hex file

COPY %1.HEX COMX
