Is there any command available in your Topsec device to make it not display the 3 "banner" messages below?
Topsec Operating System tos_3.3.010.069C.1
Topsec Network Security Technology CO.,LTD
The new line character between these lines is being lost in this interaction. I do not see this behavior in my setup for other devices that also have some informational messages between the login prompt and the password prompt.
It is worth trying true/false for this command
<Command Name=”allocatePty” Value=”false”/>
