OK, it appears you got more info than I had originally thought. These
are step/dir drivers, and up to 4 drivers can be connected to a parallel
port. It looks like you need to connect an external 5V power supply.

There is no provision in many programs for this feature. It is not
really necessary.

Most programs have a feature to power down the drives.

Sounds like it is a microstepping drive.

Yes, with a little bit of testing, it should be enough info.
