LTZSHRCVRS - Pointer to a linked list of indirect shared receivers
This field contains a pointer to a linked list of shared receivers that wish to receive data messages from an inbound multiplexed terminal. Each entry in the linked list represents one program. If the ZCOM_LTFLAG_IMX bit in ltflag is set, the system sets up this field on a zset_rcvr (mode 0) call. All incoming messages will be received by the inbound multiplexing program, which will then route the data to each of the receivers specified in this linked list.
LTHLDQ -
This queue is a holding queue for partial messages to an inbound multiplexed terminal.
LTDHQN - Data holding queues
For use by an application program to store temporary data for each terminal. Only the queue header is stored in these fields, as the data itself is stored in the ZCOM subsystem buffers.
LTUSER -
The fields in the
LTADDR - Logical terminal address
Holds the logical terminal addressing information needed to recognize the correct logical terminal in a group of multiplexed terminals. This is a
