You can either 'Optimize connection buffer size' or increase the 'Timeout' for 'Server response timeout' in the 'Connection' tab in WinSCP to a large number like 2-3. Why when I transfer a file through SFTP, it takes longer than.
I am running a remote script with WinSCP that results in a lengthy wait between terminal responses.
I get all the intermediate output from the session with the session.OutputDataReceived() event, until it comes to a point where the remote host is silent for > 30 seconds before continuing.

This is the conversation with the remote host as captured by OutputDataReceived:
Winscp Try Turning Off Optimize Connection Buffer Size
After 'Updating AAA.....success', I expect three more lines, after various wait times.
I'm assuming the remaining output lines are from the remote host, suggesting the WinSCP session is about to time out.
I need the session to stay alive to the host until the process is complete, and I tried setting 'TimeoutInMilliseconds=60000' in the SessionOptions, but the result was then
The remote script ends with rebooting the remote host, so there is no real exit or return to a command prompt, just a final 'Rebooting AAA' message, which I can use to signal the end of the process. How can I make WinSCP hold this session up until it completes?

I have a try/catch around the session.ExecuteCommand() line. When I use session defaults, and the script reaches the pause (of around 70 seconds), I see these strings returned in OutputDataReceived:
If I use the extended session option 'TimeoutInMilliseconds = 900000', I see this:
Meaning, the ExecuteCommand() method is throwing the exception, and it only waits 60 seconds for the script to send data; the TimeoutInMilliseconds apparently only applies to the session, not to the ExecuteCommand timeout.
Here is the WinSCP debug log for the 'default' session:
