6. Repeat above steps as desired, according to additional tunnel(s) available on your product.
Tunnel – Accept Mode
Controls how a specific tunnel number behaves when a connection attempt originates from the
network. In Accept Mode, the EDS1100/2100 waits for a connection from the network. 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 and increases sequentially
for each additional serial port, if supported.
Accept Mode supports the following protocols:
SSH
The EDS1100/2100 device is the server in Accept Mode). When using this protocol, the
SSH server host keys and at least one SSH authorized user must be configured.
SSL
TCP
AES
encryption over TCP
Telnet
The EDS1100/2100 supports IAC codes. It drops the IAC codes when Telnetting and does
not forward them to the serial port.
Accept Mode has the following states:
Disabled
Never accepts a connection.
Enabled
Always listening for a connection.
Active
(If it receives any character from the serial port).
Threshold
(Appears for both Timeout
and Send Character Modes)
Send the queued data when the number of queued bytes reaches the
threshold. When the buffer fills to this specified amount of data in bytes (and
the timeout has not elapsed), the device packs the data and sends it out;
applies only if the Packing Mode is not Disabled.
Timeout
(Appears for Timeout Mode)
Enter a time, in milliseconds, for the device to send the queued data after the
first character was received. Specifies the time duration in milliseconds;
applies only if the Packing Mode is Timeout.
Send Character
(Appears for Send Character
Mode)
Enter the send character (single printable or control). Upon receiving this
character, the device sends out the queued data. The data is packed until the
specified send character is encountered. Similar to a start or stop character,
the device packs the data until it sees the send character. The device then
sends the packed data and the send character in the packet. Applies only if
the Packing Mode is Send Character.
Trailing Character
(Appears for Send Character
Mode)
Enter the trailing character (single printable or control). This character is sent
immediately following the send character. This is an optional setting. If a
trailing character is defined, this character is appended to data put on the
network immediately following the send character.
