must wait until the MT responds to the AT command before sending the second
AT command.
4. A string used by the TE to send a command cannot contain the combination of
quotation marks and commas (confusing a parameter with a string). The current
version does not support escape character. The code value of a data format in
the UCS2 encoding is reported as characters. For example, if the UCS2 code of
a Chinese character is 0x553a, the 553a is reported.
A possible response sent by the MT to the TE consists of Information text and
Result code, in which Information text is optional and Result code is mandatory.
The format of a possible response is controlled by the ATV command. For details,
see the description of the ATV Command. In this document, all possible responses
listed in tables follow the ATV1 format.
