    MULTIPLE CLIENT SOCKET CONNECTIONS IN PARALLEL. THE TPNS TCP/IP
    FULL SERVER SUPPORT IS ENABLED WHEN A DEV WITH TYPE=STCP AND
    STCPROLE=SERVER ARE CODED AND NEW OPERANDS BACKLOG=N OR
    MAXCLNTS=N IS ALSO CODED WITH AN 'N' VALUE GREATER THAN ONE.
    SAMPLE DATA SET MEMBER TCPFSDOC DOCUMENTS THIS NEW SUPPORT.

    TCP/IP Full Server Support for Simple TCP/IP ( STCP )
    simulations provides a means for simulating servers supporting
    multiple client socket connections in parallel.  The TPNS TCP/IP
    Full Server support is enabled when a DEV with TYPE=STCP and
    STCPROLE=SERVER are coded and new operands BACKLOG=n or
    MAXCLNTS=n is also coded with an 'n' value greater than one.
    Sample data set member TCPFSDOC documents this new support.
    Also, information message ITP433I can now be inhibited.

Problem conclusion

Temporary fix

Comments

  • BACKLOG=1-32767 (1 default) and MAXCLNTS=1-1999 (1 default)
    operands added.  If BACKLOG=n or MAXCLNTS=n value greater than
    one, enable TCP/IP Full Server support for
    DEV TYPE=STCP,STCPROLE=SERVER.  LISTEN() on LOCLPORT=n port
    number and ACCEPT() socket connections up to MAXCLNTS=n value
    in parallel.  Allow ITP433I to be inhibited.
