(SC41–5444).i5/OS™ asynchronous communications support allows an iSeries™ application program to exchange data with a remote system or device using either an asynchronous (start-stop) or X.25 line. iSeries application programs can be written in ILE COBOL/400®, ILE RPG/400®, ILE C/400®, or FORTRAN/400 languages. Asynchronous communications support includes file transfer support (also used with other communications types) and interactive terminal facility (ITF). Asynchronous communications support provides program-to-program and program-to-device communications between systems that use asynchronous (start-stop) or X.25 lines. For X.25 lines, it also supplies an integrated packet assembler/disassembler (PAD) (1) that follows CCITT recommendations X.3, X.28, and X.29.
Asynchronous communications support allows you to send data to and receive data from a remote program or device attached by either an asynchronous (start-stop) or an X.25 line. Your application program must provide the data stream required by the remote device. Asynchronous communications support packages your data stream in either a start-stop format or within X.25 data packets.
