Raven EDGE/GPRS for Cingular - User Guide, version 2.31 22
Data Communication and Host Modes
If Q=1 (Quiet On), no result codes are output whatsoever, so there is no response generated by
a (non query) command.
If Q=0 (Quiet Of
f), result codes are output. The format of this output is then affected by the
Verbose setting.
If Quiet mode is off, the result code is af
fected as
follows:
For V=1 (Verbose mode), the textual result code is surrounded by a carriage return and new
li
ne. Any AT query response is also surrounded by a carriage return and new line.
For V=0 (Terse mode), a numeric result code is output
with a single trailing carriage return (no
new line is output), while any AT query response is followed by a carriage return and new line
(there is no preceding output).
For example, possible outpu
t
to the AT command "AT" with carriage return (assuming quiet mode
is not on) is:
carriage return - if V=0
carriage return and new line OK another carriage return and
new line - if V=1
PassThru Mode
Issuing the "AT\APASSTHRU" from a terminal emulation enters this mode. The modem responds
with OK, at which point a direct connection to the internal hardware is established.
With Wireless Ace, you can configure a string of A
T
commands to be sent to the Raven when it
enters PassThru and other PassThru settings.
FIGURE 2. Wireless Ace: PassThru
In PassThru mode, the Raven does not behave normally, all port communication is
passed directly
between the internal hardware and the computer connected directly to the modem. This mode can
be used to configure hardware-specific settings (for example, provisioning, troubleshooting, com-
municating with legacy equipment,
etc.).
Y
ou can configure MD to have the Raven enter PassThru on start up.
