6100 MPS-B Programming Manual
INTRODUCTION TO 6100 MPS-B
Line Configuration Options
MPSBAUTODISABLE (1 byte) specifies that a station in the poll
list is disabled following a normal read operation completion.
The value must be 255.
This saves processing time because the application need not issue
a Control Disable Station request to allow for host transaction
processing. However, the application must issue a Control Enable
Station request when it is appropriate to do so--for example,
after having completed a transaction and responding with a WRITE
request.
MPSBNONSTOPOFF (1 byte) specifies that synchronization between
the line task and the host is not supported by the CLIP. The
value must be zero. This is the default.
MPSBNONSTOPON (1 byte) specifies that synchronization between the
line task and the host is supported by the CLIP. The value must
be 255.
MPSBNONSTOPON indicates that synchronization between the line
task and host is supported. The last READ/WRITE request
processed is saved in CLIP memory. The request ID is used for
synchronization. This is similar to the use of "sync ID" in
the GUARDIAN file system. Retaining only one last READ and one
last WRITE request in CLIP memory can be viewed as a
synchronization depth of 1 (one for READ and one for WRITE).
When the line task receives a new READ/WRITE request, it
compares the request ID with that of the last request
processed. Status of the last request processed is returned
only if the new request and the saved request have the same
request ID.
