INTRODUCTION

Direct machine-to-machine interaction represents the

next logical extension of the internet. Cermetek internet

modem (iModem) products are designed to exploit the

internet to facilitate the utilization of machine-to-

machine interactions. Using email, information can

easily be transferred between systems and can be

transmitted/retrieved at will. Internet email provides low

cost, near real time multi-path communication.

Replacing conventional modems and long distance

telephone lines with local access internet connections

reduces fixed asset and maintenance costs, limits

communication expenses and saves money.

USER FRIENDLY INTERFACE LAYER

All Cermetek iModem products contain a user friendly

interface layer that provides the user transparent

access to the internet. This interface layer, consisting

of various @T® macro commands, has the look and feel

of conventional modem AT commands. With the @T®

macro commands the user can direct the iModem to

compose, edit/modify, send, retrieve and delete email

messages. Internet and email activity status is reported

via the iModem’s V.24 (EIA 232-E) serial interface.

COMPARISON OF CH21XX iMODEM DEVICES

The CH2165 represents the next generation in internet

enabled devices. This product provides the user with

unsurpassed command and control capabilities. The

CH2165 communicates asynchronously with the host

controller (via the serial port) and the internet (via the

PSTN connection) simultaneously. Consequently, the

user can intersperse CH2165 specific management

commands with internet commands. Further,

commands can be queued. The CH2165 will also send

or retrieve email messages of virtually unlimited length

by using streaming email techniques. The CH2165 is

ideal for applications where larger data transfers are

required and/or where large amounts of data must be

stored locally on the iModem device.
