My function keys do not work

Depending on the termcap or terminfo file on your specific Unix host (and what is used by your application on the Unix box), you might need to change the definitions for the function keys F1 to F12. These definitions are not standardized in the Unix world. The VT220, VT300 and SCO-ANSI terminals are a bit better in this regard than VT100 or ANSI.

We recommend to try a VT220 or VT300 as a first step. The terminal type string will also influence what the application expects from the key definitions.

If you need to fix only a few keys, one approach is to try all the F-keys with Alt, Ctrl and Shift combinations to see if some other key contains the definition you need. A better method would be to look at an existing working product, to see what the definition of that key should be. But the correct method is to examine the termcap, terminfo and applications on the Unix side to see what they need.

The screen layout is wrong

Problems with the screen layout might be caused by many configurable aspects. Various operating systems and their applications have different requirements that will affect how application’s screens appear in the InetVTx00 emulator screen. Unfortunately it is impossible for us to supply a golden bullet that will work everywhere.

Please play around with these settings on the Setup | Settings dialog: the number of lines on the screen (24 or 25), the wrapping and CR/LF translations. They will solve most problems. The only other common mistake is to select the wrong screen font. The line draw characters (for boxes on the text screens) are mapped differently in different fonts. We recommend Inet or Terminal fonts. In rare cases a Courier font will also work. Do not use a proportional font like Arial or Times Roman.

To change the size of your terminal screen, first change the size of your screen font. Then you may use the View | Resize option to set the screen size optimised for your selected font.

Less common problems may relate to the VT/SCO/Ansi settings. We recommend VT on, SCO off and Ansi on for the most common scenarios. The “Scroll back Rows” is an enhancement and may confuse some applications. Set your Scroll back Rows to zero.

The color instructions sent from the server may vary depending on the terminal type used. Your terminal will only go into 132-column mode if the proper command was sent from the server. I.e.: Esc[?3h and to return to 80-column mode Esc[?3l

Once you are happy with the settings, you may save this configuration under a unique name and create a short cut to always launch and connect you to the selected host.
Hint: You may also create more than one shortcut (e.g. to connect to different hosts) using the same configuration.
