AT Command Set
TC35-ATC-01-V02.10 Page 19/145 02.10 / 23.05.2001
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
OK
Parameter
<value> 0 Echo mode off
1 Echo mode on
Reference
V.25ter
Note
1. In case of using the command without parameter, <value> is set to 0.
2. Echo is disabled with the start of multiplex mode (see AT+CMUX, pg. 67).
Therefore echo is not available on logical channels: ATE0 responds with OK,
ATE1 responds with ERROR.
2.12 ATH Disconnect existing connection
Execute command
ATH[n]
Response
Disconnect existing call from command line by local TE and terminate call
OK
Note: OK is issued after circuit 109 (DCD) is turned off (RS-232 level), if it was
previously on.
Parameter
<n> 0 disconnect from line and terminate call
Reference
V.25ter
Note
If multiplex mode (AT+CMUX) is used:
ATH terminates every data call, even if it is issued via logical channels 2 or 3.
This behavior is in accordance with ITU-T V.25 ter; (07/97, see „6.3.6 Hook con-
trol“: "ATH is terminating any call in progress.")
