The text windows control group works with the various NuMorse text display windows. Here are the controls and their functions.


Code source wrap to start: NuMorse can play code from text files. When the end of the text file is reached code will either stop or start again from the beginning. This controls what will happen.


Clear Sent window on code start: If this option is set then NuMorse will clear any text in the code sent window each time the code is restarted. If the option is not set then the code characters are appended to any existing text.


Clear Typed window on code start: If this is set then any characters you previously typed will be cleared when the code is restarted otherwise your typed characters will simply be appended to existing text.


Note: If you set the Clear Sent and Clear Typed options then in Drill sessions you will always be presented with a clear typing area for your typed text . If these options are not set then you will type at the end of any previously typed text. Also, your score would be based on your most recent drill session plus typing in previous sessions. This is not normally what you would want.


Sent&Typed max sizes: This feature prevents the text in the Sent and Typed windows from gradually expanding to enormous sizes. If maximum size is reached then new characters will be added to the end of the text, while the oldest characters at the start will be discarded.


Code speed.

This group determines if NuMorse code speed will vary and by how much.


Constant:Code speed does not vary.


Speed up: The code speed gradually increases over time. The rate of increase is controlled by the Sensitivity setting.


Speed adapt:Code speed changes depending on how many errors you make in Drill mode. It slows down if you make a number of errors and speeds up if you make no errors. The speed increase is determined by the Sensitivity setting while the Threshold setting controls how many errors are needed to trigger a speed change response.


Show code elements.

This gives you the option of displaying the code element sound-alikes 'dit' and 'dah' or as graphical dots and dashes.


Session time alarm action.

NuMorse can send code for specified time periods or after a specified number of characters are sent. These options control what happens at the end of the time period or character count.


Stop: The code stops at session end if this option is checked. If this option is not checked the specified session end event will occur, but code will then continue to play.


Sound alarm: An alarm sound will play. The sound to be played is displayed below this option and you can select a different sound by clicking on the File Selecter button and choosing an audio file.


Code start delay, seconds. If this is set to a none-zero value a short delay will occur after pressing the Code Start button. A small thermometer type display above the Start button will display the count-down progress.


Preset speeds.

These buttons allow you to select two preset speeds. Set the code speed in the usual way by using the code and text speed sliders. Then click one of the preset speed buttons. The stored speed will be displayed on the button. You can recall preset speeds using the buttons next to the speed sliders in the main program window.


Show Prosigns.

Certain special characters are used in Morse code to indicate conditions such as "end of message" and so on. These are called prosigns (procedural signals) They consist of two or more code characters played "back to back". NuMorse can display these character groups in the conventional way, with a bar over the characters, or substitute single characters can be used. This option determines how the commonly used prosigns are displayed.
