High Speed HSPA-H4 AT Commands Reference Guide (Document S000483A) 8

Result Code. This is a numeric or text code that is returned after all commands (except resets)—text codes

are returned if verbose responses are enabled. Only one result code is returned for a command line

regardless of the number of individual commands contained on the line.

Response. This term indicates a response from the modem that is issued prior to a result code. Reading

registers or issuing commands that report information will provide a response followed by a result code

unless the command generates an error.

Responses and result codes from the modem, or host system software prompts, are shown in this font:
