Hi,
Thanks for testing it out.
From what I was checking SFTP does not have any special flags to handle ASCII file differently.
I also dont do any special handling of data when I receive it so it may be it a server configuration that does that.
I never heard anybody complaining about this issue before.
Can you try it on different servers and see if you have similar behavior? In case you still want me to take a look it.
Thanks,
Oleg
