flash is a demo program. It flashes the drive LED. flash works with 1541, 1570 or 1571 drives. A 1581 drive is not supported.
For Linux, flash is not installed automatically. You have to
compile it yourself (found in
demo/flash/) if you want to use it.
For Windows, it is part of the binary distribution.
This demo program does not allow you to specify a specific adapter/plugin. Instead, it always uses the default plugin.
The optional parameter device is the device number of the drive which
should flash its LED. If not specified,
flash utilizes drive 8.
