n=60, 120, or 240 depending on what is entered in the Block Transfer Size parameter (refer to the
configuration file).
Blocks in the range of 5001 to 5006 are used for Port 1, and blocks in the range
of 5101 to 5106 are used for Port 2. The last digit in the block code defines the
number of commands to process in the block. For example, a block code of 5003
contains 3 command indexes that are to be used with Port 1. The Command
index parameters in the block have a range of 0 to 99 and correspond to the
master command list entries.
The module responds to a command control block with a block containing the
number of commands added to the command queue for the port. The following
table describes the format for this block.
