Question

How was inter-country communication done during Harappan Civilization​

Answer 1

Proto-Dravidian (the ancestor of all known Dravidian languages) was probly spoken by the Early Harappans, say c. 3200-2600 BCE. Its roots -- which are beyond reconstruction -- of course go back to the origins of human language, as is the case with any other language: every language is equally old in this sense.
