7.2.3 PassThru
Mode
In PassThru mode, the RLXIC-SG 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
.
Tip:
PassThru can only be exited by resetting or power-cycling the modem. This mode cannot be
entered via a remote Telnet session.
You can configure a string of AT commands to be sent to the RLXIC-SG when it
enters PassThru, and other PassThru settings.
PassThru Mode allows only specific AT commands. Some ALEOS commands
will be unavailable when the RLXIC-SG is in PassThru mode. The commands
usable also depend heavily on the modem model number (found on the label on
the top of the RLXIC-SG).
Note:
Some internal hardware requires upwards of 20 seconds before AT commands can be
entered, so be patient if there seems to be no response to AT commands.
