|Post-initialization value:||0 (disabled)|
|Change takes effect:||After reboot|
|Relevance conditions:||Current Transport Protocol (TP) [setting/ parameter]= 1 (TCP) AND|
current Link Service Login (TL) [setting /parameter ] = 0 (disabled)
|First introduced:||Earlier than "baseline" V3.14/V3.51|
Data Login defines whether command-phase TCP programming is enabled or disabled.
This setting is irrelevant when the current Transport Protocol (TP) [setting / parameter ] is 0 (UDP) because command-phase programming is only possible when TCP/IP is used for data connections between the network host and the DS.
Command-phase programming is disabled automatically when current Link Service Login (TL) [setting /parameter ] is 0 (disabled).
