(1) The WiPort NR embedded device server sends the "Terminal Type" upon an outgoing connection.
(2) A password is required for a connection to the serial port from the network.
(3) The TCP connection closes even if the remote site does not acknowledge the disconnection.
(4) When there is a network connection to or from the serial port, the state LED turns off instead of blinking.
(5) When
Ctrl D
or Hex 04 is detected, the connection is dropped. Both Telnet mode and Disconnect with
EOT must be enabled for Disconnect with EOT to function properly.
Ctrl D
is only detected going from the
serial port to the network.
(6) When modem_control_in transitions from a high state to a low state, the network connection to or from the
serial port drops.
Flush Mode
The FlushMode (buffer flushing) parameter controls line handling and network buffers
with connection startup and disconnect.
