SSH ChannelReceiveUntilMatch() does not work after upgrade

I am attempting to upgrade from ChilkatDotNet4.dll version 9.4.1.0 to 9.5.0.58 but the following code no longer works:

sshCK.SendReqExec(channelNum, "type \remote_host_Bshare_name$data.csv && echo Get_Complete"); sshCK.ChannelReceiveUntilMatch(channelNum, "Get_Complete", "ansi", false);

I am connecting to Windows host A via SSH and then having host A print the contents of a remote file on host B, and then append the keyword "Get_Complete" so I know where the data ends.

Here are my observations:

1) This works fine with 9.4.1.0 (i.e. ChannelReceiveUntilMatch() returns true) 2) If I ignore the error and call GetReceivedText(), the data that is returned is exactly what I expected to receive. 3) I tried playing around with ReadTimeoutMs, but regardless of its value the command always returns in about 25ms.

Has this command changed significantly since 9.4 and I just need to change my logic? Or is there a bug of some kind?

Thanks, Richard
