The way to avoid this is specific to the shell and the computer you are using; in all cases, however, be sure to check whether it is a batch job before executing stty commands.

If you're using the sh, ksh, or bash shell on Big Red, you can do this by inserting the following three lines into your .profile around the offending commands:
