BSC 2780/3780 Link
Configuration Options
Note
This chapter, along with Chapter 5 and Appendix B, should be
read by programmers who are interfacing an application program
to a BSC 2780/3780 environment. If you are programming
BSC 3270, refer to Chapter 3, Chapter 4, and Appendix A.
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 5.4.1.4 on page 120.
Ta ble 6 –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
Except where noted in Ta ble 6 –1, 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.
