OVERVIEW VT100 provides an 80 column by 24 line full-screen emulation of the DEC VT-100 terminal. VT100 is designed to complement the built-in 'Comms' app, and many of the menu options and hot-keys will be familiar if you have used 'Comms'. VT100 supports most of the features of the real terminal, including: forward and reverse scrolling, highlighting, underline, inverse video, graphic box characters, keypad emulation, insert/overwrite mode, autowrap, Delete and Enter key mapping, full serial port and handshake configuration, clear screen, reset terminal, tab settings, full cursor movement, line and block erase... the list goes on and on! There is no 132 column mode, nor double size characters. The viewing mode is "full-screen": there are no zoomable fonts. In addition, VT100 allows you to save the current terminal settings between sessions, log incoming data to a file, pause the screen, and get help on the various options. INSTALLATION To install VT100 from a PC, connect Psion to PC using 3-link, start Remote Link on the 3a, and type MCLINK on the PC. Then type (on the PC) COPY VT100.APP REM::M:\APP\ This copies the VT100 application to the internal (M:) disk of the 3a. Install VT100 on the Psion system screen like any other application: Select the Install menu option from the system screen, locate Vt100.app in the application list, and then press Enter. GETTING STARTED Make sure the 3-link serial link is plugged into the 3a, then start VT100 from the System screen by pressing Enter when the highlight is on the VT100 icon. The screen should be empty, apart from a status line along the bottom. Select Special/Port and Special/Handshakes to configure the serial communications, and away you go! Press for assistance with options. NUMERIC KEYPAD As there is no numeric keypad on the 3a, the VT-100 keypad is mapped onto the main keyboard. The key turns on keypad mode for one character An indicator on the status line shows when keypad mode is toggled "on". After , press a key from the left-hand table to generate the keypad key from the right-hand table: 3a VT100 emulator DEC VT-100 keypad 1 2 3 4 pf1 pf2 pf3 pf4 q w e r 7 8 9 - a s d f 4 5 6 , z x c 1 2 3 . 0 . It soon becomes second-nature, and there is a diagram in the help system. You can cancel by pressing it again. MENU OPTIONS File Save Settings (psion-o) Saves the current terminal options into the file M:\DAT\Vt100.cfg. These settings are reloaded next time VT100 is started. To get back to a "clean" set of defaults, select Screen / Reset terminal, followed by File / Save settings. Capture (psion-c) Starts logging of incoming data to a file chosen from the file selection dialogue. You can choose to overwrite the file, or append to the end of it. When logging is in progress, this option changes to "Capture off". Select "Capture off" to stop logging. Screen Pause screen (psion-w) Stops the display of incoming data temporarily. If handshaking is being used on the serial link, then no data will be lost. An indicator on the status line shows that the screen is paused. Press a key to resume. Clear screen (psion-y) Clears the screen and resets the cursor to the top left corner. Reset terminal (psion-t) Sets all the VT100 parameters back to the "factory default" settings. The serial port configuration is not affected. VT100 Emulation (psion-e) This option allows you to set various VT100 emulation parameters: the first option listed is the default setting. Background Normal / Reversed sets black on white or white on black display. Insert mode Replace / Insert characters either overwrite or are inserted before existing ones. Autowrap Off / On determines cursor action upon reaching the right-hand edge: by default, characters after the 80th on a line overwrite the 80th. Turn it on to get automatic wrap-around onto the next line. Newline / determines action of incoming character - either cursor down, or cursor down and back to left-hand margin. Cursor Visible / Hidden hiding the cursor slightly increases display speed. Origin mode Absolute / Relative determines whether cursor positioning commands are interpreted as absolute screen co-ordinates or relative to the current cursor position. This is unlikely to need altering. Special Port (psion-j) Sets the serial port options: baud rate, data bits, stop bits, parity, ignore parity. Handshakes (psion-k) Sets the serial port handshakes: xon/xoff, rts/cts, dsr/dtr, dcd. Translates (psion-f) Enter key / / determines which characters are transmitted when the Enter key is pressed. Delete key / determines which character is transmitted when the Delete key is pressed. Keypad Mode Numeric / Application toggles the keypad (+key) keys between their "numeric" values and their "application" key codes. An application will normally enable application mode automatically when it needs it. Note that PF1..PF4 (+1..4) are not affected by the keypad mode. About VT100 (psion-a) Reminds you of our email address for support and the version number of your copy of VT100. Exit (psion-x) Leave VT100. Current settings will only be saved if you explicitly save them with File / Save settings.
