4.5 Console login via GSM dial-in
During normal operation the G-router connects the GSM modem directly to the RS-232 port on
the back of the G-router unit. For this example we assume that the G-router is connected to the
console port of the (Cisco) WAN router as shown in Figure 3. Dialing in to the unit connects the
dial-in session directly to the console port of the Cisco router. When you use a dialer to connect
to the G-router typing the dial string should get you connected to the unit.
For example:
atd 06158xxxxx
CONNECT 115200
Online 00:00

Escape usage: <ESC> character is <CTRL>\ or 0x1c
--------------------------------------------------
<ESC><ESC> -> Send escape sequence
<ESC>. -> Disconnect
<ESC>l -> Login to GSM device
<ESC>h -> Show this usage
<ESC>b -> Send BREAK command to console
Before the GSM modem is connected to the console port of the WAN router the G-router displays
a menu with options. These options can be accessed during the dial in session by giving an
escape sequence. For example to show the menu again you can type “
<CTRL>\
“followed by “
h
”.
Pressing RETURN connects you directly to the console port of the connected WAN router. You will
see the output of the WAN router scroll by followed by the router prompt.
For example:
*Mar 1 00:00:11.051: %LINK-3-UPDOWN: Interface Ethernet0, changed state to up
*Mar 1 00:00:11.055: %LINK-3-UPDOWN: Interface Serial0, changed state to down
*Mar 1 00:00:11.423: %LINK-3-UPDOWN: Interface Serial1, changed state to down

By pressing “
<CTRL>\
“ followed by “
l
” (Lower case L) escapes you out of the connection with the
WAN router and gives a login prompt of the G-router router itself. By logging in (analog to the
examples in paragraph 4.1) you get access to the configuration of the unit.
