Automatic Retry in Script

I am using a combination of a saved session and a script to upload a file.

Here's my script:

# Automatically answer all prompts negatively not to stall
# the script on errors
option batch on
# Disable overwrite confirmations that conflict with the previous
option confirm off
lcd c:\winnt
# Upload the file to current working directory
put test.txt
# Disconnect
close
# Exit WinSCP
exit


Now, when I connect to the server, it's always slow, so it asks me: "Wait for another 15 seconds?"

Once I hit "R" to retry, it connects successfully. How can I incorporate this into my script, so I don't always have to be the one pressing "R"?

Thanks for your help!

I suppose that you open the session via command line parameter, so before the "option batch on" takes effect. Use command "open" instead and place it after the "option batch on".
