ASCII
Overview
ASCII Command Protocol
(ACP) allows
the
user
to talk
directly
to the
device
without
a DLL
or special
application. The serial Prox communicates using ASCII commands. Printable ASCII commands
at
9600
baud, no
parity
1
stop
bit,
and no echo, can be sent
to the device.
Note: USB devices
that
are
virtual COM port
do
not
need
the
baud rate set. The
input is
buffered
by
the
device and executed when a carriage
return
(
CR)
or
line feed line feed (LF)
is
t
yped.
The
unit
then parses
the
command and performs
the
operation, and displays
the
results
or error
code.
“\r\nRF
IDeas>” where
\r
represents a CR and
\n
represents a
LF
that
displays on
the
command
line.
All
commands begin
with the
prefix
rfid:
and end
with
a Return key, CR
or
LF
.

the
serial
COM
port.
If it is
a CDC
virtual port,
open
the
newly installed device
that
was
created.
Linux
Most
Linux distributions include Minicom. Download
putty
(
www
.putt
y
.
or
g
) to
communicate
with
the
serial device
if Minicom is not available.
After the
USB CDC device
is
enumerated on
the
Linux machine a device
of
either

is
found
in the

Minicom
users may have
to
create a symbolic
link from

using
the
command
