SSH Timeout for slow Login prompt

[newzealandman]

We're trying to connect to a shell that only displays the login prompt after around 20s, so it creates a timout situation while waiting for the prompt. Is there a way to adjust this?

in release v1.3.0 that should be going to the beta builds in the near future, then eventually to the stable builds (https://github.com/bitfocus/companion-module-generic-ssh/releases/tag/v1.3.0) I added a feature that allows you to specify the "Handshake timeout in ms" field within the module. This is the timeout for the SSH handshake that should now be configurable. If you test this out and this fixes your issue, let me know and then I can close this issue.

Haven't progressed on this unfortunately... We're running v3.5.2 now and I have set handshake timeout to 20000. When I use my terminal I can connect using admin@10.9.200.106 and have to wait approx 17s until the prompt asks me for the password.
