AT+i Command Set When the BDRF parameter contains a fixed baud rate, iChip initializes to the specified baud rate without entering auto baud rate mode. Commands issued by the host must be sent using that baud rate in order to be recognized. In this case, iChip can be forced into auto baud rate mode by holding the special input signal low for not more than five seconds following power-up. iChip dial-up mode only: When the BDRM parameter is set to an a value, iChip assumes the attached modem has the auto baud rate feature. Once the hostiChip baud rate is determined, the iChipmodem baud rate is set to the same rate. Any other BDRM value is used as a fixed baud rate to the modem. 1.7 Reset via Serial Link Issuing a BREAK signal on the host serial link effectively resets the iChip. A BREAK signal is issued by transmitting a LOW (zero value) for a period that is longer than 23 bits at the current baud rate. Considerably lowering the host baud rate (300 baud or less) and transmitting a binary zero generates a BREAK signal. After a BREAK signal is issued, iChip requires 4 seconds to complete the reset cycle before commands can be issued. When iChip is configured for auto baud rate, the BREAK method is especially useful to force iChip back into auto baud rate mode when iChip and the host lose synchronization. 1.8 Internet Session Hang-Up Procedure (Modem Only) Upon completion of a dialup Internet session, the iChip automatically executes a modem hang-up procedure: The DTR line is dropped. After a 1 second delay, iChip raises the DTR. If the modem responds to the DTR drop with a No Carrier then Done. Otherwise, iChip issues a (+++) to the modem followed by ATH. 1.9 Modem Startup Following power-up and baud rate determination, iChip in dial-up mode issues the AT command to the modem to configure the modem‘s baud rate.

2 General Format AT+i[[ | #UFn]…] General Format (or ) 2–4 letter command code () or parameter name () Delimiter: '=', '~', '?', ':', ‗,‘ Optional parameter or data. If includes a , as defined above, it must be enclosed in single (‗) or double (―) quotes. The terminating is considered as a terminating quote as well. #UFn User-field macro substitution Carriage Return line terminator (ASCII 13) 2.1 AT+i Commands by Category Command Function Parameters/Description AT+i Command prefix Required to precede all commands Host Interface En Echo Mode n=0 Do not echo host characters n=1 Echo all host characters (default upon power-up) This command is equivalent to and interchangeable with ATEn. =value -or- :value Parameter Database Maintenance Set parameter value stored in parameter in nonvolatile memory. retains set value indefinitely after power down. ~value Assign single session parameter value value is assigned to parameter for the duration of a single Internet session. Following the session, the original value is restored. ? Read parameter Parameter value is returned. =? Parameter allowed values Returns the allowed values for this parameter. FD Factory Defaults Restores all parameters to factory defaults. Status Report RP Request status report Returns a status report value based on . Connection BDRA Auto baud rate mode Forces iChip into auto baud rate detection mode. UP Connect to Internet Forces iChip to go online, establish an Internet session, and optionally register its IP address. TUP Triggered Internet Enters a mode in which iChip goes online in response to session mode triggers from external signals. It also supports a special Always Online mode. DOWN Perform a software reset Performs a software reset. Forces iChip to terminate an Internet session and go offline. PING PING a remote system Sends a PING message and waits for its echo response.
