Direct Memory Access.  The IEEE-1284 port under ECP mode can transfer 
huge blocks
of data to/from system memory without CPU intervention.  This is great 
for parallel port
Ethernet (thankfully now replaced with USB) and par port page scanners, 
and printers,
etc.  It is much less likely to be useful for servo motor control as the 
blocks being transferred
are going to be quite short.
