The Last String in a Dial Script
The last entry in the Dial Command Script must be a Reply
string that indicates that the remote location is ready to begin
receiving network packets. This activates the TCP/IP protocol
coming from the NETServer.
When connecting to a remote NETServer for example, the final
reply string to look for should be "SL/IP" or "PPP". For other
routers, consult the product's own documentation.
Dial Script Example
The following Dial Command Script is an example of how to
establish a connection between two NETServers which have
modems supporting the AT dial command syntax:
Send
ATDT16155551234\r
\r
my_location_name\r
my_password\r
The 16155551234 would be replaced by the actual telephone
number of the remote modem.
my_location_name would be replaced by the actual user name for
your location.
my_password would be replaced by the actual password set up at
the remote site for that user name.
ASCII carriage return
ASCII line feed
octal digit XX (such as \O7)
single backslash (\)
