Functional Description
3.2.2.3 SerialNET Mode
iChip LAN SerialNET mode extends a local asynchronous serial link to a TCP or UDP
socket across the LAN or internet . Its main purpose is to allow simple devices, which
normally interact over a serial line, to interact in a similar fashion across a network,
without requiring any changes in the device itself. iChip LAN contains a set of associated
operational parameters, which define the nature of the desired network connection. iChip
LAN supports both Server and Client modes in SerialNET mode. AT+i commands are
not required to operate SerialNET mode. Thus, SerialNET mode may be used in existing
systems with little or no need to modify the application program.
3.2.3 Remote Internet Firmware Update
New firmware may be uploaded from a remote location using standard Internet protocols.
iChip LAN accepts Emails with new firmware attachments, as well as firmware uploads
from a remote browser through iChip LAN’s Web server.
3.2.4 Local BUS connection to an Ethernet LAN controller
iChip LAN interfaces an Ethernet LAN controller connected to its 16-bit local BUS.
3.2.5 Host Connection
iChip LAN can interface a host processor through one of two methods: Serial or Parallel.
3.2.5.1 Host Serial Connection
iChip LAN 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, DTR,
and DSR lines, is supported.

CO661AL-L supports standard baud rate configurations from 2,400 bps up to 230,400
bps on the host asynchronous serial communications channel. The default baud rate may
be changed permanently by using the AT+iBDRF command. Auto baud rate setting is
supported for all baud rates except 230,400.
3.2.5.2 Host Parallel Connection
iChip LAN supports an 8-bit parallel BUS interface with some additional logic. The
parallel BUS may be defined as an 80x86 (Intel) BUS or an MC68xxx (Motorola) BUS.
Note:
1: 230Kbps is available only from iChip LAN firmware version 704.
