CHAPTER 5: DOS Software Installation: UCTP and MPSDOS
In the “Redirection” column on this screen, the default for the phantom
ports COM5 to COM9 is “NONE” (no redirection). Because the PC can’t
have physical output ports with those names, COM5 through COM9 have no
assigned output port if you do not choose to use them. Also, when a phantom
port is redirected to any Multiport Spooler VIII port (“PORT1” through
“PORT12”), each job earmarked for that phantom port is transmitted to the
Multiport Spooler VIII with a string that causes the MPS-VIII to send the job
to the chosen MPS-VIII output port.
If you select the “STRING” redirection option, another screen will appear
at which you can define a character string for any phantom port. See
Section 5.3.8
.
The table below shows a sample port-redirection setup. LPT1 is the
computer port linked to the Multiport Spooler VIII. Since phantom ports
can’t be redirected to the physical port connected to the MPS-VIII, LPT1
doesn’t appear in the table. In this example, dedicated peripheral devices
are directly connected to the PC’s COM1, LPT2, and LPT3 ports.
