Telnet (The EDS supports IAC codes. It drops the IAC codes when Telneting
and does not forward them to the serial port).
Accept Mode has the following states:
Disabled (never a 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
Modem emulation
Disconnect Mode
Disconnect Mode ends Accept Mode and Connect Mode connections. When
disconnecting, the EDS shuts down connections gracefully.
The following settings end a connection:
The EDS receives the stop character.
The timeout period has elapsed and no activity is going in or out of the EDS.
Both Accept Mode and Connect Mode must be idle for the time frame.
The EDS observes the modem control inactive setting.
Note : To clear data from serial buffers on disconnect, enable “Flush Serial Data”.
Packing Mode
Packing Mode takes data from the serial port, groups it together, and sends it out to
nodes on the network. The groupings may be configured by size or by time intervals.
The following settings are configurable for Packing Mode:
Disabled
Timeout: The data is packed for a specified period before being sent out.
Specifies the time duration in milliseconds; applies only if the Packing Mode
is Timeout.
Threshold: When the buffer fills to this specified amount of data in bytes
(and the timeout has not elapsed), the EDS packs the data and sends it out;
applies only if the Packing Mode is not Disabled.
Send Character: The data is packed until the specified send character is
encountered. Similar to a start or stop character, the EDS packs the data
until it sees the send character. The EDS then sends the packed data and
the send character in the packet. Applies only if the Packing Mode is Send
Character.
