Configure Connection Settings Dialog Box (VT)

Getting there

Open a VT terminal session.
Under Host Connection, click Configure Connection Settings.

From this dialog box, you can specify the settings for a VT connection.

Connection Method


Network	Configure a host connection through a network.
Serial Port	Configure a host connection through a serial port on your PC.
Modem	Configure a host connection through a modem. The modem must first be configured in Windows.

Network

These options are available only when you have selected Network under Connection Method.

Network Connection Type


Telnet	Select to use your PC as a virtual terminal over a TCP/IP connection. When Telnet is the selected protocol, you can configure secure connections using Kerberos or SSL/TLS.
Secure Shell	Select for secure, encrypted communications between a trusted host and your PC over an insecure network. When you select Secure Shell, all connections between your PC and the remote host(s) are encrypted, protecting the data sent between these machines.
Rlogin	Select to use your PC as a virtual terminal over a TCP/IP connection.

Connection Options


Host name/IP address	Identify the host to which you will connect. Type the host name, alias, or numeric IP address. NOTE: Both IPv4 addresses (in the form 127.0.0.1) and IPv6 addresses (in the form 2001:0db8:3c4d:0015:0000:0000:abcd:ef12) are accepted.
User name	Type a name that identifies you or your PC to the host. This option is enabled only for Secure Shell or Rlogin connections.
SSH configuration scheme	Type a descriptive name to label these connection settings, making them available for use with other Secure Shell sessions. If you leave this field blank, and make changes to any connection settings, Reflection saves the configuration scheme using the value from the Host name/IP address field.
Handle SSH User authentication in terminal window	For Secure Shell connections, display user name and password prompts in the terminal window instead of in a dialog box.
Security	Secure data communications with Kerberos, Secure Shell, SOCKS, or SSL/TLS.
More Settings	Configure additional settings.

Serial Port

These options are available only when you have selected Serial Port under Connection Method.


Serial port to use	Reflection detects available serial ports on your PC and displays them here.
Parity	Set the parity for data transmission to and from the serial device on this port. This setting determines whether a parity bit is generated for each character transmitted. Parity is used to detect errors in data transmission; the number preceding the slash indicates the number of data bits sent. To use the multinational character set or 8-bit controls, Parity must be set to one of the values that offers 8-bit controls. If your communications link generates parity, and you set Parity to 8/None, multinational characters appear on your screen. In this case, set Parity to either 8/Even or 8/Odd.
Baud	Set the rate at which Reflection transmits and receives data through the selected serial port. The baud rate setting must match the baud rate of your direct connection.
More Settings	Configure additional settings.

Modem

These options are available only when you have selected Modem under Connection Method.


Modem to use	Reflection detects modems configured on your PC and displays them here.
Phone number	Type the phone number you want the modem to dial when connecting. The number must adhere to the rules of your modem.
Use country code and city code	Select this option if you want to specify a country code and city code (or area code) for the number you are dialing. Clear this option if you do not want to use the Country code, City code, and Current location options.
Country code	Type the country code for the country you are calling.
City code	Type the city code or area code for the location you are calling.
Current location	Select the previously defined location from which you are calling. These locations are defined from the Dialing Properties dialog box.
Dialing Properties	Add, modify, or remove a location from the Current location list.
More Settings	Configure additional settings.

Connection Action

You can configure a session to run a macro, start an application, open a Web page, send an e-mail message, or perform a variety of other actions before or after it connects to the host.


Run a macro or other action before the initial connection	Select to run the connection action after the session file is opened but before the session initially connects to a host. (This action is performed even if the session is not configured to connect automatically.)
Select Action	Click to select an action to perform or a macro to run before you connect to the host. By default, the Select Action window opens at the screen for selecting a macro. If you prefer to perform a different action when your session connects, you can select other actions from the task pane.
Run a macro or other action after the initial connection	Select to run the connection action when the session initially connects to a host.
Select Action	Click to select an action to perform or a macro to run when you connect to the host.
Run when reconnecting	Select to run the connection action when the session initially connects to a host, and every time it reconnects to the host.

Connection Options


Automatically connect to the host	Select to establish a host connection as soon as the associated session document is opened.
Allow exit while connected	Select to allow closing the workspace when a session is connected to a host.
When connection is terminated	Specify options for reconnecting after any disconnection that is not initiated from Reflection. Available Options: Reconnect automatically: Attempt to reestablish the connection. Prompt for reconnection: Prompt whether to attempt to reestablish the connection. (When No is selected, the session is left open and disconnected.) Leave disconnected: Leave the session disconnected with the session open. Close session automatically: Close the session.

Under Host Connection, click Configure Connection Settings.
Under Connection Method, select Network.
Under Network Connection Type, select Telnet.
Under Connection Options, click the More Settings button.

The options are:


TCP port	Most Telnet hosts wait for an incoming connection on TCP Port 23. If your host uses a different port, type that number here.
Parity	This setting determines whether a parity bit is generated for each character transmitted. Parity is used to detect errors in data transmission; the number preceding the slash indicates the number of data bits sent. To use the multinational character set or 8-bit controls, Parity must be set to one of the values that offers 8-bit controls. If your communications link generates parity, and you set Parity to 8/None, multinational characters appear on your screen. In this case, set Parity to either 8/Even or 8/Odd.
Terminal type	To override the default terminal, select or type a value here. In general, you control the following characteristics when you change terminal types: Which screen control sequences the host sends to Reflection to format the screen. The position of the cursor. Which characters to display in a host application. If you're having trouble running a host application, the negotiation between Reflection and the host might be wrong. If you enter a terminal type that the host does not recognize, Reflection reverts to a list of default values until one is found that the host supports. This option is not available if you are connecting to a network modem over Telnet.

If you enter a terminal type that the host does not recognize, Reflection reverts to a list of default values until one is found that the host supports.
Timeout	Specify the number of milliseconds Reflection should attempt to make a connection before timing out. The maximum value is 65535. The timeout period begins after host name resolution has taken place. This means an additional delay, usually a few seconds beyond the value specified. When this is set to 0 (the default), Reflection timeout behavior is determined by your Windows operating system.
Session limits	Select the maximum number of sessions you want to allow for a Telnet connection.
Close on disconnect	Select to close your session document when you disconnect from the host.
Set host window size	Select to send the number of rows and columns to the Telnet host whenever they change, so that the host can properly control the cursor if the window size is changed.
Dynamic terminal size	Select to support dynamic update of the number of rows and columns in the display when the user resizes the terminal window. Your Telnet server and application must also support NAWS (Negotiate About Window Size), otherwise display problems can occur. NOTE: You can quickly determine the screen size of the terminal window whenever you hover the mouse cursor over the Row and Column indicator (located in the left corner of the status bar).

More Settings Serial Port Dialog Box

Getting there

Open a VT terminal session.
Under Host Connection, click Configure Connection Settings.
Under Connection Method, select Serial Port.
Under Serial Port, click the More Settings button.

Note

Modem pacing is set from the More Settings - Modem dialog box.

Pacing

It is possible for Reflection to transmit data to a serial device faster than the device can process it, or for a serial device to transmit data to Reflection faster than Reflection can process it.

Should this continue for too long, the slower system\'s buffer overflows and data is lost. If the serial device recognizes the XON/XOFF handshake, you can prevent the buffer from overflowing by keeping this value set to Xon/Xoff.

Xon/Xoff transmit pacing works as follows:

When the receive buffer has a limited amount of space left, an XOFF (DC3) character is sent as a signal to stop transmitting.
After processing most of the backlog of characters in the receive buffer, an XON (DC1) character is sent as a signal to resume transmission.

The two systems continue in this stop-and-go fashion until all the data has been transmitted.

If Hardware is selected, the RTS and CTS pins on the RS-232 serial cable control data flow.

When both the Receive and Transmit options under Pacing are set to None and you're emulating a VT series terminal, Hold Session (VtF1) has no effect.


Transmit	Select a flow control method to use when Reflection transmits data to a serial device on this port.
Receive	Select a flow control method to use when the serial device on this port transmits data to Reflection.
Char transmit delay	It is possible for Reflection to send data to the host faster than the host can receive it. For example, if you paste text from the Clipboard into a host editor such as EDT, you may overrun the host's buffer. By setting a delay between characters, you can specify how long Reflection should wait after each character when transmitting blocks of characters to the host. This delay also affects character transmission during file transfers. Setting a value of 3 at 9600 baud lowers the effective speed of data transmission to about 2400 bits per second. On a VMS host, setting the terminal's HOSTSYNC characteristic can also help prevent overrunning the host's buffer when pasting data. To do this, enter the following command at the DCL prompt: `SET TERMINAL/HOSTSYNC`. For backward compatibility, you can enter a value for character delay of up to 255. However, the maximum in Reflection always reverts to 100.
Line transmit delay	Set the amount of time Reflection should wait after transmitting a carriage return character (the line delimiter) before transmitting the next line. This setting also affects the delay between frames during file transfer using the WRQ/Reflection protocol. Assigning a delay may help if you are experiencing file transfer problems over an X.25 connection.
Use threaded I/O	Select to send communication calls to an independent thread that handles IO (Input/Output) processing, thus improving performance.

Advanced Tab (More Settings Telnet Dialog Box)

Getting there

Open a VT terminal session and then open the Settings dialog box.
Under Host Connection, click Configure Connection Settings.
Under Connection Method, select Network.
Under Network Connection Type, select Telnet.
Under Connection Options, click the More Settings button.

The options are:


Session limits	Select the maximum number of sessions you want to allow for a Telnet connection.
Terminal default	Type a value to send as a backup to the Telnet server if the server requests this information, and doesn't recognize the current value set for Terminal type. NOTE: During negotiations, some hosts that could successfully connect using your preferred terminal type skip over this value during negotiations and connect using the backup value specified by Terminal default. To correct this behavior, set Terminal default to an empty value ("").
Bind to local port	Select to choose a specific local port for Reflection to connect through to communicate with the host. If this option is cleared, Reflection will use the next available port.
Local port	Specify a local port. If this option is set to zero, Reflection uses the next available port.
Send LF after CR	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 (in this case, Reflection). There are some hosts on the Internet that are not true Telnet hosts, and they expect to see a `Lf` (line feed) character following the `Cr` at the end of a line. If you're connecting to this type of Telnet host, select this option.
Telnet location	(Optional) Type up to 41 characters of descriptive text to provide information about your session. For example, you might include your PC's location, computer name, or IP address. This features uses the SEND-LOCATION option supported under Telnet connections (RFC779). Reflection does not initiate a WILL SEND command unless you activate the Telnet location option by typing information in this box.

More Settings Modem Dialog Box

Getting there

Open a VT terminal session.
Under Host Connection, click Configure Connection Settings.
Under Connection Method, select Modem.
Under Modem, click the More Settings button.

The settings in this dialog box control the modem currently selected in the Modem to use list. If you switch to another modem, these settings will then apply to that modem.


Connection mode	Select an action to take when making a modem connection. CALL: Dial the remote host specified in the Phone number box. AUTO-ANSWER: Connect to the modem and wait for the first ring of an incoming call before answering. ANSWER: Connect to the modem and immediately answer any incoming call. DIRECT: Connect to the modem so you can enter modem commands in the terminal window. DIALBACK: Dial the remote host specified in the Phone number box, disconnect, then wait for a return call. Use this setting if you are using a security dialback host.
Baud rate	Set the rate at which Reflection transmits and receives data through the selected modem. The default baud rate is that specified in Windows Control Panel, from the Modem Properties dialog box, defined when you installed your modem. When connecting to a host via modem, you may need to select a different baud rate. The maximum baud rate is a function of many factors, such as the type of modem you have and the quality and length of the communications line.
Parity	Set the parity for data transmission through this connection. This setting determines whether a parity bit is generated for each character transmitted. Parity is used to detect errors in data transmission; the number preceding the slash indicates the number of data bits sent. To use the multinational character set or 8-bit controls, Parity must be set to one of the values that offers 8-bit controls. If your communications link generates parity, and you set Parity to 8/None, multinational characters appear on your screen. In this case, set Parity to either 8/Even or 8/Odd.
