9.2.1 Definitions

In this chapter, the following naming conventions are used:

• Data Communications Equipment (DCE) – Refers to the Wi-Fi module.
• Data Terminal Equipment (DTE) – Refers to the terminal that issues commands to the Wi-Fi module.

The DCE interfaces operates in one of two modes:

• Terminal mode – In this mode DCE waits for AT commands and interprets all received characters as commands to execute. All commands must be terminated with a literal <CR><LF> and these characters must not appear anywhere else in the command/parameter input stream. Parameters can be exchanged in one of two forms to accommodate binary data or infrequently-used ASCII control characters.
• Raw mode – In this mode the DTE transfers and accepts data in its original form without any modifications (in other words, in binary format without any post- or preprocessing).
