2.7.3 Closing the Data call
2.7.3.1 Exit the data mode and enter the command mode
• Send escape sequence +++
• wait the escape sequence pause time ( see S12 parameter)
• wait for response 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.
