Parameter
script-name: The name of Modem script.
script-content: Script content.
Description
Using the script-string command, you can configure a Modem script. Using the
undo script-string command, you can cancel the Modem script.
By default, the system does not have a Modem script.
3Com series routers provide the Modem script, which is mainly used for:
Providing flexibility in controlling the Modems of different models. For example,
using different initialization strings can make the Modem of different
manufacturers or models to better interoperate with the 3Com series routers.
Implementing the interactive login to remote systems. Interactive negotiation of
the scripts can enable the systems enter different link states. For example, after
the asynchronous serial interfaces on the two routers set up a connection via the
Modems, the routers can negotiate the protocol to be encapsulated with the
physical link and its operating parameters.
The Modem script format in common use is as follow:
send-string1 receive-string1 send-string2 receive-string2 ......
Among the above format:
send-string indicates a sending string.
receive-string indicates a receiving string.
Normally, send-string and receive-string appear in pairs, and the script must
begin with a sending string. For example, send-string1 receive-string1 ......
represents the execution flow: Send send-string1 to the Modem and expect to
receive receive-string1. If the string matching receive-string1 is received before
timeout, the execution of the subsequent script, which will be otherwise
terminated, will continue.
If the last string is a sending string, it indicates that the execution of the script will
be terminated after the string is sent without waiting for any receiving string.
If the beginning of the script needs no sending string, but need to wait for
receiving string directly, the first string can be set as "", the meaning of which will
be explained later.
