LEDs light) - then back to Port A.
Note: Broadcast is only operational if all ports are connected to online printers. The printers must be
of the same model and have the bidirectional function disabled.

Software to select the ports under 1-to-4 Mode is provided on the distribution diskette that came with
this package. You may use Hot keys under DOS, or click on the AS icon under Windows. See the
