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.
reader command
A reader command causes the reader to perform a task. You can enter a reader
command by typing on the keypad, by scanning a bar code label, or by sending
a command from the host computer.
Reader Services
A collection of programs on the reader that decode bar codes, process data
input and output, configure the reader, and handle power management.
reader-to-reader
A method of communicating between two readers. By placing two readers so
the receive signal on one reader aligns with the transmit signal on the other
reader, and the transmit signal on the first reader aligns with the receive signal
on the other reader, you can achieve direct communications between the two
readers. For this type of communications, the readers should be no more than
1 inch apart.
records per block
The maximum number of data records transmitted per block of data. A block
of data is transmitted during a single transmission event.
regular label
A bar code label that takes the form of <start code data stop code>. A regular
bar code label is executed as soon as you scan it. Contrast with multiple-read
label.
remark out
When you add a REM statement (short for REMark) at the beginning of a
command line in a batch file, DOS treats the line as a remark instead of as a
command. Any statement beginning with the characters REM will be ignored
by the command processor. Typically, users will remark out device drivers in
AUTOEXEC.BAT and CONFIG.SYS startup files.
REQ
Request for Acknowledgment character. Sent by the reader to the host to
request a retransmission of an acknowledgment to a reader message.
