Turn off Optimize connection buffer size

Is there a way to do this in the script? I tried using "option optimize connection buffer size off" but this is throwing an error.

Thanks.

I've been trying to get this to work in a SSIS 2005 Execute Process Task but keep getting the message "Unknown command -rawsettings"

I'm using it as the first line of my script like so: -rawsettings SendBuf=0

Is there a different way I should be using this?

Thanks,

Keith

The -rawsettings is not a command, but a switch to open command:
https://winscp.net/eng/docs/scriptcommand_open

I've added an example:
https://winscp.net/eng/docs/rawsettings#example

I have this below statement in ssis script task which calls winscp and passes below command

open sftp://<<User Name>>:<<Password>>@<<Domain>>:21 -rawsettings SendBuf=0 -hostkey="<<hostkey>>"

Host is not communicating for more than 15 seconds. Still waiting...
Note: If the problem repeats, try turning off 'optimize connection buffer size'

Please help

Please attach a full log file showing the problem (using the latest version of WinSCP).

For some reason, the site I connect to doesn't work well with the "Optimize connection buffer size" enabled, and whenever I had that on while downloading files larger than a few megabytes, I'd get this error: Server unexpectedly closed network connection.

Fortunately, I found how to turn it off and (in the GUI version at least) all my transfers are successful. On the contrary, in batch mode from a script file, even after setting "-rawsettings SendBuf=0" appended to the open command, the connection will "unexpectedly close" on files larger than a few megabytes.

Does SendBuf=0 completely turn off the feature as the GUI checkbox does?

Thank you.
