Foreword
(This Foreword is not part of this Standard)
This Standard was formulated under the cognizance of TIA Subcommittee TR-30.2 on Data
Transmission Interfaces and Protocols.
This Standard is a revision of TIA/EIA-602, Data Transmission Systems and Equipment Serial Asynchronous Automatic Dialing and Control. ITU-T Recommendation V.250
(formerly V.25bis) was approved by the ITU-T. The approval of V.250 was strongly backed
by U.S. participants of Study Group 16. The TIA TR-30.2 members have determined that
ITU-T Recommendation V.250 contains all of the requirements which were contained in the
first edition of TIA/EIA-602. Recommendation V.250 goes on with additional commands
which were not included in TIA/EIA-602. TIA/EIA-602-A therefore, is written to essentially
point to the ITU-T Recommendation V.250, listing those commands and options which are
contained in V.250 and apply to TIA/EIA-602-A.

SCOPE
This Standard is applicable to the interconnection of data terminal equipment (DTE) and
data circuit-terminating equipment (DCE) employing serial binary data operation via the ITUT Recommendation V.24, 100-series interchange circuits. This Standard, through reference
to ITU-T Recommendation V.250, provides four elements:
-- codifies existing practice in common asynchronous DCE that use the AT command
set. It identifies the protocol elements procedures, and behaviors that were found to be
held in common among a large portion of DCE manufacturers;
-- defines a format for extension of the AT command set in an orderly fashion. It
reserves the "+" command prefix to be used by other standardized extensions;
-- provides a set of standardized extensions, based on the extended "+" command
format.
