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<n> sets the lowest acceptable connection
speed and &N<n> sets the highest acceptable
connection speed, where <n> 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.
