Functional Description
iChip & iChip LAN Datasheet 3-2
3.2.3 Operation
All iChip Internet and parameter operations are controlled by AT+i commands.
3.2.3.1 Transparent Mode
In modem configurations, iChip CO561AD-S defaults to transparent mode, allowing the
host to control the modem device directly. Control is implemented by the host issuing
standard AT commands to iChip. In this mode, iChip CO561AD-S transparently echoes
the AT commands to the modem, as well as echoing the modem responses back to the
host. In addition, hardware flow control signals are emulated on the host side to reflect
the levels set by the modem and vice-versa. iChip CO561AD-S supports interlacing AT+i
and AT commands, while the modem is in command mode.
When the modem is put into data mode, by issuing a dial command, transparent mode is
sustained throughout the data-mode session.
3.2.3.2 Command Mode
iChip commands are implemented using the AT+i command set. Command flow exists
only on the host serial bus between the host and iChip.
3.2.3.3 Internet Mode
iChip enters Internet mode after being issued an Internet messaging command to send or
receive an Email message. iChip attempts to establish an Internet connection and carry
out the required activity through the communication platform link. While in this mode,
AT+i commands are supported to monitor and control the process when needed. All other
AT+i commands return with an I/BUSY response.
3.2.3.4 Direct Modem Firmware Update Mode
In a modem configuration, issuing an AT+iFU command enters this mode. iChip
CO561AD-S monitors the modem for an incoming call by detecting the ‘RING’
response. When called, iChip CO561AD-S instructs the modem to answer the call and
assumes a YMODEM session to receive a file containing a firmware update. The
incoming file contents are downloaded and authenticated. If the new firmware image
checks out the existing firmware is replaced in the on-chip flash memory and iChip
CO561AD-S is reinitialized.
3.2.4 Host Serial Connection
iChip supports a full-duplex, TTL-level serial communications link with the host
processor. Full EIA-232-D hardware flow control, including Tx, Rx, CTS, RTS, and
DTR lines, is supported.
3.2.5 Serial Connection to Dial-up Modem
iChip CO561AD-S supports a full-duplex, TTL-level serial communications link with the
modem device. Full EIA-232-D hardware flow control, including Tx, Rx, CTS, RTS, and
DTR lines, is supported.
