3290 Address Configuration - IBM 3274 51C Maintenance Information

5.8 3290 Address Configuration (Configuration
Supports T and D)
Each customized 3274 port has an assigned port address.
This port address is considered to be the primary logical-
terminal address for the port. To support the Multiple
Interactive Screen (MIS) function for an attached 3290
display station, the Type A port to which the 3290 is
attached must be assigned the appropriate number
(l-4)
of
secondary logical-terminal addresses in addition to the
primary logical-terminal address.
