4: BSC 3270 Link Configuration Options
DC 900-1340I 97
To set this option using the DLI configuration file, use the safeStore parameter; for
example,
safeStore = ”no”. See Table 7–1 on page 190.
4.16 Station ID Option (18)
This option determines the control unit number of a tributary station. Control units
range from 0 to 31. If the station ID is set to 32, the tributary station enters “test mode.”
See Section A.2.2 on page 196. This option is not used by links configured as control
stations.
To set this option using the DLI configuration file, use the stationID parameter; for
example,
stationID = 0. See Table 7–1 on page 190.
4.17 Message Blocking Option (19)
This option controls the logical blocking and deblocking of data between message buff-
ers and transmission blocks during normal link operation. Normally, the ICP message
buffer size (Section 3.4.1.3 on page 58) is configured to be much larger than the trans-
mission block size (Section 4.8), but this does not have to be true in order for message
blocking to work. See Section 2.1.4 on page 35 for more information on message buffers
and transmission blocks.
To set this option using the DLI configuration file, use the messageBlocking parameter;
for example,
messageBlocking = “dataBlk”. See Table 7–1 on page 190.
Note
When transparent data is received, blocking acts as if message
blocking is set to disable.
4.17.1 Blocking Disabled
If the message blocking option is set to disable, blocking/deblocking is not performed.
For inbound data, each received transmission block is treated as a separate message
