Chapter 2 – AT Commands

Command:

&En Modem-Initiated Flow Control

 

Note: For use with MT5600BA and MT5600BR only.

Values:

n = 3, 4, or 5

Default:

4

 

Description:

&E3

V.42bis data compression enabled.

 

Note: This command controls only V.42bis data compression, whereas the %C command

 

 

controls both V.42bis and MNP-5 data compression. The command in effect is the

 

 

one last entered. See also the L5 command.

Command:

&Fn Load Factory Settings

Values:

n = 0 or 1

Default:

None

 

Description:

&F0

Loads factory configuration 0.

 

&F1

Loads factory configuration 1.

 

Note: See also the Z, L5, and &V commands.

Command:

&Gn V.22bis Guard Tone Control

Values:

n = 0, 1, or2

Default:

Varies by country

Description:

&G0

Disables guard tone.

 

&G1

Sets guard tone to 550 Hz.

 

&G2

Sets guard tone to 1800 Hz.

 

Note: The &G command is not used in North America, and may not be permitted in some

 

 

countries.

Command:

&Kn Flow Control Selection

Values:

n = 0, 3, 4, 5, or6

Defaults:

3 (data modem mode)

 

6 (fax modem and voice modes)

Description:

&K0

Disables flow control.

 

&K3

Enables CTS/RTS hardware flow control.

 

&K4

Enables XON/XOFF software flow control.

 

&K5

Enables transparent XON/XOFF flow control.

 

&K6

Enables both CTS/RTS and XON/XOFF flow control.

 

Note:

See also the &E command

Command:

&Mn Communications Mode

 

Values:

n = 0–3

 

Default:

0

 

 

Description:

This command determines the DTR operating mode. The modem treats the &M command

 

as a subset of the &Q command.

 

 

&M0

Selects direct asynchronous operation. Command sequence &M0\N0 selects

 

 

 

normal buffered mode, but command sequence \N0&M0 selects direct mode. This

 

 

 

is because the \N0 command is analogous to the &Q6 command.

 

 

&M1

Selects synchronous connect mode with asynchronous offline command mode.

 

 

&M2 Note: For use with the MT5656ZDX and MT5656ZDX-V only. Selects synchronous

 

 

connect mode with asynchronous offline command mode.

 

 

 

Same as &M1 except that &M2 enables DTR dialing of directory slot 0. The modem

 

 

disconnects if DTR is low for more than the period stored in S25.

 

 

&M3

Selects synchronous connect mode. This mode allows DTR to act as a talk/data

 

 

 

switch. A call is manually initiated while DTR is inactive; when it becomes active,

 

 

 

the handshake proceeds in originate or answer mode according to S14 bit 7.
