7.2.2 AT Mode
Using a terminal connection, AT commands are used to configure the modem,
command it to do something, or query a setting. For a full listing of the AT
commands, refer to the appendix. AceManager is a graphical user interface for
most AT Commands.
 AT commands must always be terminated by <CR> (ASCII character 0x0D),
a carriage return (pressing enter on the keyboard). Some may also include a
new line or line feed <LF>.
 If E=1 (Echo On), the AT command (including the terminating <carriage
return) will be displayed (output) before any responses.
 Two settings affect the format of AT command output: V (Verbose), and Q
(Quiet).
 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 Off), 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 affected as follows:
For V=1 (Verbose mode), the textual result code is surrounded by a carriage
return and new line. 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 output 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
Note: These commands work for the port on which they are executed. For example, if the user
types ATE1, and then AT&W using a serial port connection, it will set the serial port to Echo On.
7.2.3 PassThru Mode
In PassThru mode, the RLXIC-SV 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,
communicating with legacy equipment, etc.
Caution: ALEOS is disabled in PassThru Mode. You cannot use most ALEOS specific commands
while the modem is in 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. You can also configure the modem to enter PassThru
mode on start up using MD.
