OK scpmode keepalive xxxx Keepalive activated notication
Details: xxxx = The specied timeout value (msec)
Example: Command: scpmode keepalive 2000
Response: OK scpmode keepalive 2000
Meaning: Set the timeout value to 2000 msec (2 seconds).
The timeout value was set to 2000 msec (2 seconds).
Note: When unexpected disconnection happens, remote controller can’t nish communication with closing process.
In such case, device has to keep status "connected" and remote controller can’t establish new connection after that.
In order to prevent the situation above, device watches keepalive command if connection with remote controller is still
alive.
If device doesn’t receive keepalive command within timeout value which is set by this command, device terminates
connection by itself.
After the Keepalive activation command has been activated, the Remote controller must send any command or
LF(0x0A) code as a heart beat to the device within the timeout value.
