act dvflow
This command activates a vacuum to be drawn on the drum for holding plates on
for imaging. The dvflow command opens a valve redirecting the drum vacuum pump
suction to the drum.
Only applies to old drum vacuum systems.

act dvflow on|off
The pump itself is started during power up, but can be controlled with the
"act dvpump" command.
BETA SPECIAL: Until the Beta machines are retrofitted (until this message disappears)
they are different!! The Beta machines have larger drum vacuum pumps that are turned
off after an unload and don't use any valving. The beta machines do not have a
dvflow command, only a dvpump command.
