device. AT command is not entered in online status. The only accepted command is '+++'
and this character string is not printed on the screen.
When WCS-232 receives the '+' character from the host, it stops sending and waits for the
next character. If the second character is '+' and the third character is '+', then it switches to
Command Standby status. If the second or third character is other than '+', the transfer
resumes from the first '+' character. If there is a '+++' character string in the transmission
data, there may be an unintended change in operation status.
Also, when the data transmission has stopped receiving the ‘+’ character at last, WCS-232
does not send data and wait, so you should check for abnormal operation possibilities. In
this case, AT+SETESC command can solve the problem by changing ‘+’ to another
character.
'+' is the Escape sequence character set as default. Not available in Remote mode.
*Caution: In low-power mode, the '+++' string cannot switch the mode from online to
command standby. Input of '+++' string in low-power mode in online state can cause
unexpected errors.
