z The default timeout time waiting for a receiving string is 5 seconds. TIMEOUT

seconds can be inserted into the script to adjust the timeout time waiting for the

receiving string, which is valid till a new TIMEOUT is set in the same script. For its

meanings, refer to the following table.

Table 3-1 Script keywords

Keyword Description

ABORT receive-string

The string following ABORT will be

compared with the string sent from a

Modem or a remote DTE device for a full

match. Multiple ABORT entries can be

configured for a script, and all of them

take effect in the whole script execution

period.

TIMEOUT seconds

The digit following TIMEOUT is used to

set the timeout interval that the device

waits for receiving strings. If no expected

strings are received within the interval,

the execution of the script will be failed.

Once being set, the setting will be valid

till a new TIMEOUT is set.

z All the strings and keywords in a script are case-sensitive.

z Both strings and keywords are separated by spaces. If a space is contained in a

string, it should be put in the double quotation marks (" "). A pair of empty

quotation marks (that is, "") has two possible meanings. Being a leading "" in a

script, it means that no string needs to be sent and the system will directly wait for

the receiving string. If "" is put at any other locations, the string content will be

regarded to be "".

z ABORT receive-string can be inserted anywhere in a script to change the script

execution flow. Its presence in the script indicates that the script execution will be

terminated if a received string is fully matched to the receive-string set by ABORT

receive-string. Multiple ABORT entries can be defined in a script, and they will

take effect concurrently. Once a received string matches any of them, the script

execution will be terminated. Regardless of where the ABORT receive-string is

placed, it will take effect in the whole script execution process.

z Escape characters can be inserted in a script for the purpose of better controlling

the script and increasing its flexibility. In addition, all the escape characters are the

delimiters in the string at the same time. Refer to the following table for details.
