General Tab (More Settings Telnet Dialog Box)

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.


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.


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.

Use emulation terminal ID

Select to force Reflection to ignore the Terminal type setting and instead use the value from the Terminal ID setting on the Emulation tab from the Terminal Setup dialog box.

Use threaded I/O

Select to send communication calls to an independent thread that handles IO (Input/Output) processing, thus improving performance.
