The following parameters in this page are supported:
Maximum Burst Size
This value specifies the maximum amount of data that will be transferred without
disconnecting. A value of zero sets no limit. This value is in units of 512 bytes. For
example, a value of 8 means 4K bytes. Values that are not multiples of 8 are rounded up
to the closest multiple of 8.
Data Transfer Disconnect Control (DTDC)
This value specifies the restriction when a disconnect is permitted.
