By default, the PQ-8S receives PC
data at 96N81 (9,600 baud; parity =
none; word length = 8 bits; stop bits
= 1). Make sure the PC/LAN and
the PQ-8S are using the same serial
parameters. In addition, the PQ-8’s
Serial-In settings should be
compatible with its Serial-Out
settings. When printing from the
PC/LAN, the lowest baud rate
(Serial-In/Serial-Out) will determine
the print speed. The PQ-8’s Serial-In
parameters can be changed through
Host/PC download commands 76
through 79, or through the setup
software.

If the PC print job is sent while a
host job is printing, the printer
responds as “busy” to the PC print
request. The print job can be
spooled through a spool program,
sent to the printer when the host job
is finished, or if the PC’s printer port
is set for infinite retry through the
DOS “Configure Printer” command
(described in the DOS manual), the
print job waits for the printer to be
available to receive the data.

5.1 Serial Printing
By default, the PQ-8S sends data at
96N81 (9,600 baud; parity = none;
word length = 8 bits; stop bits = 1).
Make sure that the printer and the
PQ-8S are using the same serial
parameters. The PQ-8S’s Serial-Out
parameters can be changed using
the second (right) bank of switches
located on the front panel.

5.2 Printer Sharing
The PQ-8P and PQ-8S allow the
printer to be shared automatically
between an attached PC/LAN and
an IBM twinax host. Simply connect
the PC/LAN printer server to the
parallel (PQ-8P) or serial (PQ-8S)
port. The PQ-8P can supply external
devices attached to its parallel
sharing port with 5V up to 350 mA.
See Appendix F for information on
how to transfer power to pin 18 of
the PQ-8P.

The PQ-8 uses a timeout after each
print job before it honors print jobs
from another port. At the end of a
host print job, the PQ-8 waits for
the specified Twinax Port Timeout
period before it honors data streams
coming in through the sharing port.
