1.1 Terminal Display 

This document describes the AT interface of Huawei UMTS Module MU509. The 
description on the AT interface is only limited to the interface packet itself, the usage 
and use procedure of TE and MS, and does not cover the contents which are not 
directly related to the interface. 

1.1.1 

Interface Overview 

HUAWEI UMTS Module is a wireless terminal of UART or USB interface. It is used to 
provide data service, voice and SMS functions.   

This document describes the AT interface.   

In the subsequent AT command parameters, two formats are involved: <> and [], as 
described below:   

<...>: Parameters enclosed in angle brackets must be completed. Brackets 
themselves do not appear in the command line. 

[...]: Optional subparameter of a command is enclosed in square brackets. Brackets 
themselves do not appear in the command line or response. 

<CR>: Carriage returns character, which value is specified with command S3. 

<LF>: Linefeed character, which value is specified with command S4.
