States

Enters the AT command mode with receiving “+++”
~
Keeps AC command mode

Terminates TCP connection with ATH command
~
Processes of TCP disconnection
③

~
Sends “NO CARRIER” with disconnection
EZL-200F changes the mode to AT command, when receiving “+++” and sending “OK”
message. In this state, the communication with remote host is not possible because 200F
processes only AT command. Whenever you want to go back to online state (TCP
connection), use “ATO” command.
For more information about this, please refer to the “ATC mode” on the [Support] >>
[Download] >> [Technical Document] menu of our web site.
