MULTIPORT SPOOLER VIII (4-, 8-, and 12-Port Models)
A reserved port’s LED flashes until you cancel the reservation. If a job
directed to a port is on pause, the port’s LED flashes very slowly (once every
few seconds).
Buffer Full
If the Multiport Spooler VIII’s buffer becomes full, all the port LEDs flash
until space becomes available. Note that while the buffer is full, the transfer
of data is substantially slower than normal.

PERATION
If you did not configure the Multiport Spooler VIII, did not install MPSWIN,
MPSDOS, or the UCTP, and do not use control commands to control the
MPS-VIII, the unit operates according to its default parameters. Jobs sent to
the unit go to the first available output port (4, 8, or 12). Unless you have only
one peripheral (or all your peripherals are of the same kind), this might
cause problems. If it does, we recommended that you install either MPSDOS
or MPSWIN (depending on whether you work in DOS or Windows
respectively), and/or the UCTP, so that you and your users can select
peripherals. Refer to
Chapter 5 for DOS installation instructions; refer to
Chapter 6 for Windows installation instructions.
NOTE
If you are in a DOS application and are sending a job to the MPS-VIII
through a serial port on your PC, make sure that the PC port’s
communication parameters are the same as those of the receiving
MPS-VIII input port (which by default are 9600 bps, no parity, 8 data bits,
and 1 stop bit).
If you are in DOS itself, use the DOS MODE command or the included
SMODE command utility to set the PC port’s communication parameters.
