2.7.3 Closing the Data call

+++

wait the escape sequence pause time ( see S12 parameter)

OK

NOTE: After the Escape sequence and during the call the only command that is accepted by
the GM862-QUAD / PY is the ATH. All the other commands are not supported during a call.

TIP: during the escape sequence pause time S12 no further characters should be sent to the
device in order to enter the command mode.


2.7.3.2 Hang up the data call

Send command

ATH<cr>

wait for response

NO CARRIER

TIP: during the data call the device remains in data (on line) mode, so the escape sequence
(+++) must be issued before sending AT commands to the device.
