In
1986, a dial-up link for email exchange was set up between NCST and IIT Bombay. Very soon all ERNET partners were on dial-up ERNET email and academics in these institutions started sending emails to all over the world," he said. When there was no Internet service providers in the country, public or private, ERNET informally gave email facilities to software companies, said Ramani. But what was the reaction of the common people on these pathbreaking achievements?
"In the beginning, people did not have much idea about email. A sure-shot method to convince one was to describe how easy and cost-effective it would be to contact with his/her son or daughter abroad," said Swapan Kumar De, former head, Computer and Informatics Group, Variable Energy Cyclotron Centre (VECC), Kolkata.
"In the eastern region, ERNET was first installed in VECC. From there it was spread to other institutes in Kolkata and other states," said De, the pioneer in initiating ERNET in eastern India. By 1991, the ERNET community crossed 1000 and hundreds of persons started using email in these sites, said De, adding that at that time, the initial investment to have ERNET mail was around Rs 30,000, without a printer.
