HUAWEI UMTS M2M Module AT Command Interface Specification Confidential 16 Appendixes 16.1 Appendix 1 AT Command Description 16.1.1 Basic Commands The format of a basic command is: [] Where, is a single letter (A-Z) or a “&” plus a single letter, and is a decimal number composed of one or more digits. The 0s at the head of will be ignored. If a basic command that can carry carries no , the value is 0 by default.
HUAWEI UMTS M2M Module AT Command Interface Specification Confidential indicates multiple parameters, separated by “,” in the middle. For the parameters that have a default value, they can be omitted and substitute the default value. If all the parameters are omitted, the “=” behind should be omitted too. If is not identified, it indicates that this command does not exist, and the information “COMMAND NOT SUPPORT” will be returned.
HUAWEI UMTS M2M Module AT Command Interface Specification Confidential 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.
