CSW-M85 changes the mode to AT command, when receiving “+++”. In this state, the
communication with remote host is not possible because M85 processes only AT
commands. Whenever you want to go back to on-line state, just give “ATO” command.
For more information about the AT commands, please refer to the “AT Command
mode” document on [Download] >> [Technical Document] >> [Basic and common
parts] category of our web site.
