Extended Attribute Buffer (EAB) is used by devices for highlighting, such as reverse video,
underline and blinking text.
The Feature Memory Allocation panel displays the amount of feature memory available for
PS storage based upon the values defined in other fields. Any feature memory left over after
all other feature memory has been defined will be allocated to PS Storage.
The following sections document the PS Storage memory requirements for various features.
You should verify that your LINCS node has sufficient PS Storage memory to support these
features:
• Multiple Logical Sessions (MLS)
• Print Buffering
• ASCII Setup
• ASCII Cut and Send
• LPD Server sessions
We also provide a Presentation Space Storage Memory Worksheet, which you can use to help
calculate LINCS memory needs for Presentation Space.
Multiple Logical Sessions (MLS)
The memory required for MLS is used to maintain screen images and information for each
configured session. The screen image memory required is determined based upon the mod
size of the device as indicated in Calculating Presentation Storage Space. In addition to the
screen image for each session, 1K of memory is required to maintain information about the
session.
