Abort Attribute; Appendix 2 Cme Error List - Huawei EM770W At Command Interface Specification

indicates that this command does not exist, and the "COMMAND NOT SUPPORT"
information will be returned. If <name> is identifiable, and the command contains
uncalled-for parameters, or the number of parameters goes beyond the defined range,
the information "TOO MANY PARAMETERS" will be returned.
z
Command format:
<name>?
The READ command is used to read the current value of the parameter.
z
Command format:
<name>=?
If the MS cannot identify <name>, the information "COMMAND NOT SUPPORT" will
be given. If the MS can identify <name>, and the command carries no parameter, the
information "ok" will be returned. If the command carries parameters, the value range
of each parameter will be returned first, then "OK" will be returned.

21.1.4 Abort Attribute:

Abort means the TE sends an instruction to interrupt a command being executed. The
"Abort" command must be issued before the command finishes execution, so it makes
sense only to the commands that require a certain time period for executing. However,
not all commands that require a certain time period for executing can be aborted,
depending on the abort attribute of the command. Each AT command has the abort
attribute. This attribute is a two-option choice. Namely, the command either supports
abort or does not support abort. The commands that support abort include some
basic commands and the EXECUTION command of action command. These
commands do not accept any abort request within 125ms after being issued. After the
command has been issued for 125ms but has not finish execution, if any character is
received from the TE, it will interrupt the execution of the command immediately.
The commands that support abort are as follows:
atD
atA
at+CLCK
at+COPS
at+CLCC
at+CLIP

21.2 Appendix 2 CME Error List

Note: The following table lists the possible CME errors and reasons for all the
interface command. The code in the first row of the table represents the <err> value of
CME ERROR. The numerals in the table represent the sequence number of reasons.
The table of correspondence between CME ERROR and text string is attached later,
together with detailed description on the reasons.
