Hi SagarSB,
I am not really sure what interferes with the connection (based on session connection method, it is COM interface attach or attaching through the EHLL Dynamic Link Library) - it can be that there are security rules (antivirus, Group Policies) that are not allowing UiPath processes to do that and it would be hard for me to check those remotely.
As a workaround, please try the agnostic approach as described in the PDF attached here: Connection To BOSaNOVA - #2 by cornel
it has to do with regular UI Automation so the type and nature of Terminal Application is not relevant for as long as it is a native Windows app.
