and lithium backup battery.
preamble
Predefined data that is automatically appended to the beginning of entered
data. Similar to postamble.

protocol handler
A protocol handler provides communications services that let a reader send
data to other devices by transmitting and receiving data as specified by the
communications protocol. The basic reader can use PHIMEC and PHPCSTD.
RF readers can also use RFPH.
PSK
JANUS Programmer's Software Kit. A library of software functions for creating
applications on the JANUS.
PSS
Program Statement Separator character. The PSS indicates the end of an IRL
program statement. It separates individual IRL program statements from one
another in a block of IRL program statements. PSS must not be defined the
same as the EOM.
PutImage
One of two programs you can use to change the contents of drive C. PutImage
places an image file created with MkImage on the reader. You can run
PutImage only on the reader.
RAM
Random access memory. Memory that can be written into, or read, by locating
any data address.
RAM drive
A disk drive that exists only in your reader's extended memory. You create,
read, write, and delete files on a RAM drive the same way you can on a hard
disk drive. RAM drives are faster than hard disk drives because the contents of
a RAM drive are, by definition, always resident in RAM. The contents are
destroyed when you cold boot the reader.
