4: BSC 3270 Link Configuration Options
DC 900-1340I 93
For messages received on the communication line, the ICP message buffer size
(Section 3.4.1.3 on page 58) is the maximum size that can be received; otherwise, the
DLI_ICP_ERR_BUF_OVERFLOW error code is sent to the client application.
To set this option using the DLI configuration file, use the transBlkSize parameter; for
example,
transBlkSize = 512. See Table 7–1 on page 190.
4.9 Data Translation Option (10)
This option invokes transmit and receive data translation using one of the two onboard
ASCII/EBCDIC translation tables described in Appendix C, either of which can be
changed by issuing a Set Translation Table command (Section 3.4.1.1 on page 57). This
option is enabled only when the character set option (Section 4.7) is set to EBCDIC.
If this option is set to disable and the character set option is set to EBCDIC, no data
translation is performed, but EBCDIC control sequences are used on the line. In this
case, the client application program is responsible for performing any necessary data
translation.
When one of the translation tables is selected, data translation is enabled. Data blocks
from the client are treated as ASCII data and are translated into EBCDIC before they are
transmitted on the communication line. Conversely, data blocks received from the line
are treated as EBCDIC and are translated to ASCII before they are sent to the client. No
translation is done on transparent data blocks.
To set this option using the DLI configuration file, use the dataTranslation parameter; for
example,
dataTranslation = “table1”. See Table 7–1 on page 190.
4.10 Station Priority Option (11)
This option enables the data link to operate as either a control station or a tributary sta-
tion. If the link is configured as a control station, BSC 3270 performs polling and selec-
tion of tributary stations. If the link is configured as a tributary station, it responds only
