string.
The standard PPP dial out process can be replicated by using Modem Emulation mode
with the ‘Dialup String’ left blank and the ‘Answer String’ set to “CONNECT”.
All AT commands for dialling should be sent before the dialup String, the special
command ATDT*99***1# (or ATDT*99#) will inform the Intelimax+ to go into a PPP
exchange string mode.
In Modem Emulation mode, before the PPP connection is established, AT commands are
supported to change settings in the modem or collect information from the modem. All
standard AT commands and Maxon customized AT$$ commands are supported.
The command ATDT*99***1# is to notify the Intelimax+ to go into the PPP mode, after this
command no more AT commands are supported through direct accessing of the serial
port. To continue to use AT commands after PPP connection, AT over IP to port 12522
can be used.
The MS Chat Dial mode is to support Microsoft Windows PPP client. Before initiating the
PPP connection, it requires the exchange of the text strings “CLIENT” (from the client) and
“CLIENTSERVER” (from the serer). So in MS Chat mode, the Intelimax+ PPP server will
expect a “CLIENT” string from the client and then send back “CLIENTSERVER”.
