PPP Mode
In PPP mode, the Raven acts as a PPP server, providing an IP address, and DNS
servers (if available) to the Host.
PPP mode is entered from the AT mode by using any of the following commands:
AT\APPP <CR>
ATDT10.0.0.1 <CR>
ATDT10001 <CR>
ATD#19788 <CR>
CLIENT <CR>
In response to any of the preceding commands, the modem will respond with
CONNECT <CR><lf> and is ready for the host to begin PPP negotiations.
The IP received by the host in the resulting negotiation will either be a private (non-
routable) IP or a public (network-routable) IP provided by the network, depending
on the settings of
*HOSTPRIVMODE . If *HOSTPRIVMODE=1 , the value of
the private IP an be determined beforehand by querying S110 . The private IP to be
used can be defined with the command AT*HOSTPRIVIP=192.168.100.33 sub-
stituting the desired IP address.
AT*HOSTPRIVIP=192.168.100.33 Using a private IP insulates the PPP client
from changes in IP addresses of the underlying network. The Raven will perform
basic NAT-like address translation on all packets.
If a public IP address is being used, any changes in the IP (as determined by the
wireless network) will result in the PPP link to the host being disconnected, requir-
ing the host to reinitiate it. The public IP is passed to the host in the PPP negotia-
tions, so when the network forces a change, the modem has to force the host to
renegotiate the PPP link to make this happen.
Slip Mode
SLIP mode is entered be using the " AT\ASLIP " command. As in PPP Mode, the IP
address that the host assumes is affected by the setting of *HOSTPRIVMODE .
