When the TCP session ends, it will pause for the number of seconds specified by the Restart
Delay. The default value (and minimum value) for the Restart Delay is 1 second.
Wait for Keyboard Hit
You may configure the TCP connection to wait for a “keyboard hit” before starting the TCP
session. Enabling this mode will display a message on the serial port (after DCD is present if
DCD is required to use the port) asking the user to type a character to begin the TCP session.
Telnet Options
The following options apply only if an Outgoing Telnet Connection is configured.
Telnet Mode
The TCP service can connect to a server using the telnet protocol in either Binary mode (8-
bit) or Human mode (7 bit, performs line and character processing for terminals). The telnet
client will negotiate telnet parameters with the remote telnet server. The parameters that it
will request are as follows:
 Binary mode: DO BINARY, WILL BINARY
 Human mode: DO SUPPRESS GOAHEAD, WILL SUPPRESS GOAHEAD
The gateway also supports the following telnet modes if negotiated by the remote telnet
server: ECHO, COM-PORT-OPTION, TERMINAL-TYPE, and TIMING MARK. (Note that
the gateway does not support local echo. However, it will accept a WILL ECHO request for
remote echoing and will respond with DO ECHO.)
Terminal Type
If the remote host requests the DO-TERMINAL-TYPE telnet option, and the Terminal Type
field is configured, the gateway will respond with this value. This field is useful when you
are connecting serial terminals to the gateway and the remote host needs to know how to
format output to the terminal. Otherwise, you can leave this blank.
Quiet Mode
By default, the telnet session will display various status messages as it makes, loses, or
breaks connections to the remote server. Selecting Quiet Mode will suppress these
messages. This is useful when using serial devices that may be confused by these status
messages.
Telnet Escape Character
When the telnet client is in the 7-bit “Telnet mode”, it parses serial input for a special escape
character. The default escape character is “CTRL-]” (or ASCII 29). If it sees this character, it
breaks into the telnet command mode and displays a command prompt that allows the user
to execute some telnet session commands. You may specify a different character (as decimal
ASCII) to use as the Telnet Escape Character, or specify -1 to disable this feature entirely.
