BSC 3270 Link
Configuration Options
Note
This chapter, along with Chapter 3 and Appendix A, should be
read by programmers who are interfacing an application program
to a BSC 3270 environment. If you are programming
BSC 2780/3780, refer to Chapter 5, Chapter 6, and Appendix B.
This chapter describes the various link configuration options that can be set using the
DLI configuration file described in Section 7.2 on page 188. Alternatively, the link
options can be set using the
dlWrite Configure Link command as described in
Section 3.4.1.4 on page 59.
Ta ble 4 –1 lists all the available options in numerical order along with the allowed set-
tings and defaults. The defaults are in effect immediately after the protocol software is
downloaded to the ICP. They remain in effect until you either modify the DLI configu-
ration file and redownload the ICP, or send a
dlWrite Configure Link command.
Note
Link configuration options can be set only when the link being
configured is stopped.
Some of the possible error conditions are discussed in the following sections, as they
relate to using each configuration option. Appendix D explains BSC error handling and
gives a list of errors.
