Setting this value to 0 disables the idle

timeout (i.e. the connection will stay open
indefinitely).

Modem Init String

The initialization string sent to the modem

before each connection attempt. Use this

field to insure that the modem’s baud rate

matches the value set in Serial Port Baud
Rate. The Modem Init String for Profile 1

is sent on the serial port each time the i.LON
10 is reset.
You do not need to enter “AT” before each

member of the init string (i.e. rather than

“AT&C1;AT&F” you should enter “&C1&F”.
The default Modem Init String is
“ATE0Q0V1S0=0&C1&M1. If you are using

a US Robotics modem, it is advised that you
change this to

“ATE0Q0V1S0=0&C1&B1M1.” The B1

command causes the modem to automatically
use the bit rate used by the i.LON 10 (this

commend is not available in non-US Robotics

modems). See GSM/GPRS Service Providers

Tested with the i.LON 10 Ethernet Adapter,

later in this chapter for more information
about Modem Init Strings to use with

GSM/GPRS modems.
You can use the modem initialization string

to implement flow control (i.e. to limit the
speed of the connection). For most modems,

&U sets the lowest acceptable connection

speed and &N sets the highest acceptable
connection speed, where can be set to:
6 9600

bps

10 19200

bps

16 33600

bps

Do not use the &C0 command in either of the

Profile initialization strings. Using this

command will prevent the i.LON 10 from
initiating a dial out session.
See your modem documentation for more

information on supported init strings.

Chat Script

Only used if the ISP requires more

handshaking than a user name and

password. Each field can accept up to 63
characters.

Use Static IP Address

Set this checkbox to manually set the IP

Address, Primary DNS Server, and

Secondary DNS Server of the i.LON 10
Ethernet Adapter when connected to an ISP.
