Data Mode AT COMMANDS

Local Modem (or Test Modem)

AT&F &W<CR>	Returns the modem to the factory defaults.
AT S18=20 &T8	Causes the modem to start local analog loopback with self-test for 20
	seconds.
OK	After starting analog loopback, the modem goes back to command
	mode.
AT	The modem responds to new commands.
OK
000	After 20 seconds, the modem stops analog loopback, sends
OK	an error count to the DTE, and enters command mode.
AT S18=0 &T8	Causes the modem to start local analog loopback with self-test, which
	is only terminated by AT&T0 or ATH.
OK	After starting analog loopback, the modem goes back to command
	mode.
AT	The modem responds to new commands.
OK
AT&T0	After receiving AT&T0 or ATH, the modem stops analog
000	loopback, sends an error count to the DTE, and enters
OK	command mode.

3.10AT Escape Sequences

The 56K family provides the industry-standard Time Independent Escape Sequence (TIES). The DTE sends the escape sequence to return the modem to command state while in the online data state (that is, connected to another modem) or in diagnostic mode (&Tn commands).

Intel also makes the Hayes Escape Sequence available to customers; however, see the following statement regarding licensing requirements.

Licensing Requirements for Hayes Escape Sequence

The Intel chipsets are manufactured with TIES as the default setting. It is Hayes’ position that you must either have or obtain a valid license from Hayes Microcomputer Products, Inc., of Norcross, Georgia, before producing modem systems that use the Hayes Escape Sequence.

Intel accepts no responsibility and does not indemnify nor in any way provide protection for patent or possible patent violations to its customers or users of its products.

3.10.1Time-Independent Escape Sequence

The TIES (Time-Independent Escape Sequence), implemented with +++AT, was developed by a group of modem manufacturers as an alternative to the Hayes Escape Sequence. TIES was designed for compatibility with existing communication software written for the Hayes Escape Sequence.
