I can think of a way to do this, by writing a program (say in C) that
takes the batch file name from the command line and then redirects 
CTRL C to nothing (see Turbo C's help on signal() ) and the makes a 
call to system("batch_file_name.bat").

If you want I can send you the source code. All you need to do is to be
able to call the bach file with something like this:

ms-dos_prompt> c_program batchfile.bat


Hope it helps.
