Chapter 5 Web Configuration
 Disconnect from serial port
When EKI is in data mode, user can type the hangup character triple times,
such as “+++”. EKI will shut down the TCP connection and back to command
mode, and shows “NO CARRIER” to indicate the connection has been shut
down.
 Disconnect from remote TCP connection
When EKI shows “NO CARRIER” on serial port, it means the TCP connection
has been shut down. EKI will back to command mode automatically.
AT Commands
EKI supports the following common AT commands used with a typical modem:
Example 1 (Local connect to remote)
Example 2 (Remote connect to local)
Note! The “+++” command cannot be divided. The “+” character can be
changed in Hang-up Character, and the guard time, which prefixes and
suffixes the “+++” in order to protect the raw data, can be changed in
Guard Time (ms). See picture.
