Hello,
I need to turn off ECHO in the VirtualTerminal. Basicaly it is terminal mode ECHO 0 in the SSH channel request. Does Rebex SSH has such options?

Applies to: Rebex SFTP, Rebex Terminal Emulation

Unfortunately, encoded terminal modes are not supported in SSH_MSG_CHANNEL_REQUEST currently. However, it seems it would be easy to add this functionality.

Would you like to receive a beta version to test it?

Hello, Lukas,
Thank you for the prompt reply.
At this moment I don't have an implementation to test this feature. It would be great if you add this functionality in the further releases.

Hello,
Do you have any plans regarding the terminal modes?

Yes, it is planned to add support for sending custom SSH "opcodes". However, we don't have public API for it yet.

Regarding the original question, we have already implemented support for turning off ECHO.
It will be part of the upcoming release 2020 R3.

The "ECHO 0" opcode will be sent to the SSH server automatically, when TerminalOptions.LocalEcho = true.
