2.11 ATE Enable command echo

Write command

ATE[<value>]

This setting determines whether or not the TA echoes characters received from
TE during command state.

Response

Parameter

<value> 0 Echo mode off

1 Echo mode on

Reference

V.25ter

Note

In case of using the command without parameter, <value> is set to 0.

2.12 ATH Disconnect existing connection

Execute command

ATH[n]

Disconnects any call in progress, such as voice, fax or CSD calls. See notes be-
low for GPRS and multiplex mode.

Response

Note:

OK is issued after circuit 109 (DCD) is turned off (RS-232 level), if it was previ-
ously on.

Parameter

<n>

0 terminate call

Reference

V.25ter

Note

Using ATH in Multiplex mode (AT+CMUX):
· ATH terminates every voice, fax or CSD call, no matter on which channel ATH

was executed.

For example, if ATH is executed on channel 2 or 3, a voice call made on chan-
nel 1 will be disconnected, too.

This behaviour is in accordance with ITU-T V.25 ter; (07/97, see “6.3.6 Hook
control“: "ATH is terminating any call in progress").

Using ATH while GPRS is active during Multiplex mode:
· ATH clears an active PDP context or terminates an existing PPP connection,

but only if issued on the same logical channel where GPRS is used. It does not
affect PDP contexts and PPP connections on other channels.
