Lantronix EDS32PR User Manual

C: Networking and Security
EDS Device Servers User Guide 163
Connect Mode has six variations:
 Disabled (no connection)
 Enabled (always makes a connection)
 Active if it sees any character from the serial port (makes a connection upon
receiving any character)
 Active if it sees a specific (configurable) character from the serial port
 Modem emulation (controlled by modem commands)
 Modem control asserted (makes a connection when the modem central signal on
the serial line becomes active)
For the “any character” or “specific character” connection states, the EDS waits and
retries the connection if the connection cannot be made. Once it makes a connection and
then disconnects, it does not reconnect until it sees any character or the start character
again (depending on the configured setting).
Accept Mode
In Accept mode, the EDS waits for a connection. The configurable local port is the port
the remote device connects to for this connection. There is no remote port or address.
The default local port is 10001 for serial port 1, 10002 for serial port 2, 10003 for serial
port 3, and so forth.
Accept Mode supports the following protocols:
 SSH (EDS is the server in Accept Mode). For this protocol, the SSH server host
keys and at least one SSH authorized user must be configured.
 TCP
 Telnet (IAC)
 AES encryption over TCP
Accept Mode has the following options:
 Disabled (close the connection)
 Enabled (always listening for a connection)
 Active if it receives any character from the serial port
 Active if it receives a specific (configurable) character from the serial port (same
start character as Connect Mode’s start character)
 Modem control signal (when the modem control on the serial line corresponding
to the tunnel becomes active)
Disconnect Mode
Disconnect mode ends Accept mode and Connect mode connections. When
disconnecting, the EDS shuts down connections gracefully.
The following three settings end a connection:
 The EDS receives the stop character.
 The timeout period elapses and no activity is going in or out of the EDS. Both
Accept mode and Connect mode must be idle for the time frame.
