Example of the message terminal screen
To operate the Message Terminal program you will need to know which keys to press. Now we will explain the functionality of the special keys on your keyboard. A Window is an area of the screen with a double-line border. There could be several windows displayed on the screen at the same time overlapping each other. The window on the top will have a shadow. This indicates that the next keystroke on the keyboard will be directed to this window .
The Title shows the name of the window.
The Menu Bar contains the menus of a window. Text Field is the part of the screen where you may type in text. The Status Field is a field showing the current ocean region and status information. When the transceiver is logged in and not performing a Scan, Login, Logout or a Link Test, the current ocean region is displayed. GPS Mode Indicates the mode of the GPS. The GPS mode consists of three levels; Acquisition, 2-D or 3-D and will be indicated by using the 0-3 square boxes shown in the table below.
The INM-C Signal Meter indicates a satellite signal strength of 0-5 using square boxes. The scale is indicated by 5 small dots. 3 boxes or more are needed to make reliable communication. The Clock shows the system time. Hint Field may show miscellaneous status information or hints about which key to press. This will be 'Space' for Spacebar and 'Enter' for the Enter key.
