5.4 VT connection settings

In addition to the common connection settings, VT hosts require these additional settings:

Table 5-4 VT session configuration options

VT Settings	Description
Terminal ID	This setting determines the response that Reflection ZFE sends to the host after a primary device attributes (DA) request. This response lets the host know what terminal functions it can perform. The Reflection ZFE response for each Terminal ID is exactly the same as the VT terminal's response; some applications may require a specific DA response. This terminal ID setting is independent of the Terminal type setting. The options are: VT220, VT420, VT100, DEC-VT100, and VT52.
Local Echo	Automatic (default). How Reflection ZFE responds to remote echo from a Telnet host: Automatic attempts to negotiate remote echo, but does what the host commands. Yes means Reflection ZFE negotiates local echo with the host, but always echoes, while No means Reflection ZFE negotiates remote echo with the host, but does not echo.
Renegotiate Echo	No (default). When set to Yes, passwords are not displayed on the local screen, but all other typed text is visible. Reflection ZFE supports the Telnet Suppress Local Echo (SLE) option when connected to a host in half-duplex mode. This means that Reflection ZFE will suppress character echo to the host computer, and with SLE support Reflection ZFE can be instructed to suppress echo locally.
Set Host Window Size	Yes (default). This setting sends the number of rows and columns to the Telnet host whenever they change. This enables the Telnet host to properly control the cursor if the window size is changed.
Request Binary	No (default). Telnet defines a 7-bit data path between the host and the terminal. This type of data path is not compatible with certain national character sets. Fortunately, many hosts allow for 8-bit data without zeroing the 8th bit, which resolves this problem. In some cases, however, it may be necessary to force the host to use an 8-bit data path by selecting this check box.
Send LF after CR	No (default). A "true" Telnet host expects to see a CrNu (carriage return/null) character sequence to indicate the end of a line sent from a terminal. There are some hosts on the Internet that are not true Telnet hosts, and they expect to see a Lf (linefeed) character following the Cr at the end of a line. If you're connecting to this type of Telnet host, select Yes.
Ctrl-break sends	Choose what sequence Ctrl-break sends to the host when pressed. Options are: Telnet break sequence (the default), Interrupt process, or Nothing.
Host Character Set	The default value for the Host character set depends on the type of terminal you are emulating. This setting reflects the current terminal state of VT Host Character Set, which can be changed by the host. The associated default setting, saved with the model is DEC Supplemental.
Auto Answerback	No (default). This setting specifies whether the answerback message (set with the Answerback property) is automatically sent to the host after a communications line connection.
Answerback String	This setting allows you to enter an answerback message if the host expects an answer in response to an ENQ character. The answerback string supports characters with codes less than or equal to 0xFFFF via Unicode escape sequences. The escape sequence begins with \u followed by exactly four hexadecimal digits. You can embed Unicode escape sequences in any string. For example, this embedded \u0045 will be interpreted as this embedded E, since 45 is the hexadecimal code for the character E. To pass Unicode escape sequences to the host, escape the sequence with a leading backslash. For example, to send the string literal \u001C to the host, map a key to \\u001C. Reflection ZFE will convert this to the string \u001C when that key is pressed and send the 6 characters of the resulting string to the host.
Display columns	80 columns (default). Specifies the number of columns to display.
Display rows	24 rows (default). Specifies the number of rows to display.
