Faster, more efficient business information exchange among manufacturers, financial service firms, and government agencies will result from a new agreement to be announced in San Francisco today between Spectrum Concepts Inc of New York City, and Control Data Corp, Minneapolis. Anyway, that is what the two partners believe. The pact will enable Electronic Data Interchange customers to use IBM’s LU 6.2 data transmission protocol in addition to others when connected to Control Data’s Redinet public data network, by virtue of Spectrum Concepts’ XCOM 6.2 implementation of IBM LU 6.2 definition. Companies use Redinet for preparing, transmitting and receiving invoices, purchase orders, shipping forms, and other business communications, electronically: the service was launched in 1984 as a US-wide net for industrial users. The XCOM 6.2 package enables peer-to-peer communications over Redinet between customers’ IBM mainframes. Hitherto, bisync communications protocols have been used.
