3488 Mode Commands
DBW <slot><port>,#I<block data>
Outputs a block of data to the specified digital I/O port. When DBW is
received, the 3499A/B/C will interpret the block of data to be output
according to the slot/port parameters and DMODE (polarity, handshake)
command.
The slot parameter is a decimal ranging from 0 to 9 (mainframe
dependent). Valid slot numbers are:
3499A slots 0 through 5
3499B slots 0 through 2
3499C slots 0 through 9
The port parameter is a number that indicates where the data is to be
read. The port is module dependent and the valid port numbers are shown
below.

In 16-bit mode, block data is interpreted as being the high byte first. In
32-bit mode (port 06), block data is interpreted as being the highest byte
first, then the second highest and so on. The transfer is completed by
setting the GPIB EOI line true concurrently with the last byte of data.
