External Modems parameters
The External Modems page contains external modem parameters. External modem support
added to GPRS builds. It is now possible to have a GPRS build that can also make outgoing PPP
connections via an external modem. It is also possible to answer incoming calls via an external
modem.
The PPP
use_modem
field has been altered so the value indicates which modem type should be
used. Value
1
indicates that GPRS modem should be used. Value
2
indicates that external modem
should be used. It is now also possible, by including enough modem call control instances, to do
multilink PPP over multiple external modems.
ASY Port
The physical ASY port for the external modem.
W-WAN mode
Enables W-WAN mode.
Initialization string n
These parameters (
Initialisation string 1
,
Initialisation string 2
,
Initialisation string 3
)
allow you to specify a number of command strings that are sent to the wireless module each
time a wireless connection is attempted. These can be used to set non-standard wireless
operating modes.
Each string is prefixed with the characters
AT
before being sent to the wireless module and
they are sent to the wireless module in the order specified until an empty string is
encountered. For example,
Initialisation string 3
will not be sent unless
Initialisation string 1
and
Initialisation string 2
are both specified. Initialization strings are
not normally required for most applications as the router will normally be pre-configured for
correct operation with most networks.
