z

connection was terminated.
z
All data from previous connection on the serial port has been transmitted.
The IOLAN has logic to automatically detect when a reverse connection is no longer
active. When this happens, the connection is reset and the server can go back to a
active. When this happens, the connection is reset and the server can go back to a
listening for an incoming connection
state.
Applications using Single Telnet need to be aware that there can be some considerable
delay between a network disconnection and the port being available for the next
delay between a network disconnection and the port being available for the next
connection attempt; this is to allow any data sent on prior connections to be transmitted
out of the serial port. Application network retry logic needs to accommodate this
feature. The default value is
