GLOSSARY
XEROX COAX/TWINAX OPTION (XCTO) PROGRAMMER REFERENCE
GLOSSARY-5
PA1
Programme Attention 1.  Key input code X'5F' is loaded into POA
location 0002 during printer-host communications after the PA1
button is pressed.  Note that this is generally done as part of an
applications programme running on the host.
PA2
Programme Attention 2.    Key input code X'5E' is loaded into
POA location 0002 during printer-host communications after the
PA1 button is pressed.  Note that this is generally done as part of
an applications programme running on the host.
PCIA
Printer Communications Interface Area.  The PCIA, which
occupies the first 50 hexadecimal bytes in the input buffer of a
coax-attached printer, contains control information.  The POA,
which occupies the first 10 hexadecimal locations, contains
printer information that is read by the cluster controller.  The
CUOA, which occupies the next 40 hexadecimal locations,
contains cluster controller information that is read by the printer.
POA
Printer Output Area.  The POA, which occupies locations 0 to
X'000F' of the PCIA, contains information regarding printer status
and configuration.  The POA is written by the printer and read by
the cluster controller.
PSF
Print Services Facility.  PSF is the print driver that converts
Systems Application Architecture (SAA) source applications data
to IPDS (Intelligent Printer Data Stream).  PSF also converts
Advanced Function Printing Data Stream (AFPDS) to IPDS.  Note:
the 4213 Laser Printer does not handle IPDS.
SAA
Systems Application Architecture.  This integrated architecture,
announced by IBM in 1987, has four main components:  1. 
Common User Access (CUA) addresses user interface issues.  2.
Common Programming Interface (CPI) addresses programming
languages and related services.  3.   Common Communications
Support (CCS), the communications component, includes the
more modern subsets of SNA.   4. Common Applications, such
as office automation.
