The connection works well with Expanse.
I'll be reaching out directly btw.
However for the group.

The most likely cause when this (or a rule/pause/at not working) is that there is text from a prior window also there – and it confuses the command. Its a long story why that can occur ( the documentation section Meditech Client Server Overview) covers how their screens "work)
The solution is to clear and refresh the screen.
This is the command that clears:
Connection.Windows.Clear
Then to refresh it, you <do something> that causes Meditech to resend all of its text.
Most of the time, you can do that by using:
Key "{F5}"
