Background display message queue size The number of entries in the queue
can be set from 20 to 255. The default is 20 entries. Enter YES to the prompt
PARM and the number of entries to the prompt NDIS. Queue size changes
will take effect only after the next initialization.
Device type and address A teletype (TTY) or video display terminal (VDT)
device is defined for Background Terminal (BGD) input/output. Each device
is assigned a physical device address (SDI port) ranging from 0 to 15. Enter
TTY xx to the prompt ADAN, where xx is the device address. The number of
devices supported depends on the system type (16 for NT, XT, 51, 51C, 61,
61C, 71, 81, and 81C systems, and 8 for ST, STE, RT, 21, and 21E systems).
Output use To define a TTY device as a Background Terminal, reply BGD
to the prompt USER. In response to the prompt CUST, provide the customer
(0–99) to whom the BGD will be assigned. Terminals may also be allowed
access to the overlay mode. However, the Background and overlay features
will interact at terminals designated to operate in this dual mode by displaying
each other's messages. In addition, the BGD can only be used for data input
or retrieval in the mode for which it is accessed.
