Script hangs on prompt to accept new host key

I have a problem when the winscp host key has been deleted on a remote machine.

Next time we connect with a script, it hangs on the prompt "The server's host key was not found in the cache. You have no guarantee that the server is the computer you think it is..."

Is there a way to get the session to time out and fail?

Thanks

Use "option batch abort" before connecting.

Thanks Martin - that works if I use open in the script.

Is there a way to get it to work if we invoke using

winscp.com xxx /script=sss

where xxx is the stored session name?

No. You should not do this at all. If you still need to pass session name on command line, you can do:
winscp.com /command "option batch abort" "open xxx" /script=sss
But make sure there are no spaces in session name.
