INTRODUCTION
HSPA+ AT Commands Reference Guide

Avoid placing several action commands in the same command line. If one command fails, an error message is
received. However, it is not possible to determine which command failed the execution.
If command V1 is enabled (verbose responses codes) and all commands in a command line performed
successfully, result code <CR><LF>OK<CR><LF> is sent from the TA to the TE, if subparameter values of a
command are not accepted by the TA or command itself is invalid, or command cannot be performed for some
reason, result code <CR><LF>ERROR<CR><LF> is sent and no subsequent commands in the command line are
processed.
If command V0 is enabled (numeric responses codes), and all commands in a command line performed
successfully, result code 0<CR> is sent from the TA to the TE. If sub‐parameter values of a command are not
accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code
4<CR> and no subsequent commands in the command line are processed.
In case of errors depending on ME operation, ERROR (or 4) response may be replaced by +CME ERROR: <err> or
+CMS ERROR: <err>.
Note:
The command line buffer accepts a maximum of 80 characters. If this number is exceeded none of the
commands are executed and TA returns ERROR.
Information Responses And Result Codes
For the previous examples, if verbose response format is enabled the terminal adapter (TA) response might
appear as:
Information response to +CMD1?
<CR><LF>+CMD1:2,1,10<CR><LF>
Information response to +CMD1=?
<CR><LF>+CMD1(0‐2),(0,1),(0‐15)<CR><LF>
Final result code
<CR><LF>OK<CR><LF>
Result codes according to ITU‐T V.25ter
Two types of result codes include:
Result codes that inform about progress of TA operation, for example connection establishment CONNECT.
Result codes that indicate occurrence of an event not directly associated with issuance of a command from TE
(for example ring indication RING).
