Binary synchronous communications

Binary synchronous communications (BSC) is a data communications line protocol that uses a standard set of transmission control characters and control character sequences to send binary-coded data over a communications line.

Binary synchronous communications equivalence link (BSCEL) support is the intersystem communications function (ICF) support on the IBM i system. BSCEL support provides binary synchronous communications with a remote system or device. BSCEL also supplies online and batch communications between application programs on different BSC systems. IBM i application programs can be written in the Integrated Language Environment® (ILE) C/400, ILE COBOL/400, ILE FORTRAN/400, or ILE RPG/400® programming languages.
