FU TERMINAL INSTALLATION page 1 of 5 Since FU uses a full screen display, efficient operation of screen functions (scrolling, and positioning to a different place in the file) depend on the following terminal functions: Erase to end of line Insert a line Delete a line If your terminal does not support these functions, they will be supplied by FU, however, screen updates will be much slower since the entire screen must be re-written. Before you use FU.COM, it must be installed to your particular terminal, i.e. provided with information regarding control characters required for certain functions. This installation is easily performed using the program FUINST.COM which is described in the following. After having made a work-copy, please store your distribution diskette safely away and work only on the copy. Now start the installation by typing FUINST.COM at your terminal. Select Screen installation from the main menu. Installation A menu listing a number of popular terminals will appear, inviting you to choose one by entering its number: ------------------------------------------------------------------ Choose one of the following terminals: 1) ADDS 20/25/30 15) Lear-Siegler ADM-31 2) ADDS 40/60 16) Liberty 3) ADDS Viewpoint-1A 17) Morrow MDT-20 4) ADM 3A 18) Otrona Attache 5) Ampex D80 19) Qume 6) ANSI 20) Soroc IQ-120 7) Apple/graphics 21) Soroc new models 8) Hazeltine 1500 22) Teletext 3000 9) Hazeltine Esprit 23) Televideo 912/920/925 10) IBM PC CCP/M b/w 24) Visual 200 11) IBM PC CCP/M color 25) Wyse WY-100/200/300 12) Kaypro 10 26) Zenith 13) Kaypro II and 4 27) None of the above 14) Lear-Siegler ADM-20 28) Delete a definition Which terminal? (Enter no. or ^X to exit): ------------------------------------------------------------------ Terminal Installation Menu page 2 of 5 If your terminal is mentioned, just enter the corresponding number, and the installation is complete. Before installation is actually performed, you are asked the question: ------------------------------------------------------------------ Do you want to modify the definition before installation? ------------------------------------------------------------------ This allows you to modify one or more of the values being installed as described in the following. If you do not want to modify the terminal definition, just type N, and the installation completes by asking you the operating frequency of your CPU (see last item in this file). If your terminal is not on the menu, however, you must define the required values yourself. The values can most probably be found in the manual supplied with your terminal. Enter the number corresponding to None of the above and answer the questions one by one as they appear on the screen. In the following, each command you may install is described in detail. Your terminal may not support all the commands that can be installed. If so, just pass the command not needed by typing RETURN in response to the prompt. If Delete line, Insert line, or Erase to end of line is not installed, these functions will be emulated in software, slowing screen performance somewhat. Commands may be entered either simply by pressing the appropriate keys or by entering the decimal or hexadecimal ASCII value of the command. If a command requires the two characters 'ESCAPE' and '=', you may: either Press first the Esc key, then the =. The entry will be echoed with appropriate labels, i.e. =. or Enter the decimal or hexadecimal values separated by spaces. Hexadecimal values must be preceded by a dollar- sign. Enter e.g. 27 61 or $1B 61 or $1B $3D which are all equivalent. The two methods CANNOT be mixed, i.e. once you have entered a non-numeric character, the rest of that command must be defined in that mode, and vise versa. A hyphen entered as the very first character is used to delete a command, and echoes the text Nothing. page 3 of 5 Terminal type: Enter the name of the terminal you are about to install. When you complete FUINSTAL.DOC, the values will be stored, and the terminal name will appear on the initial list of terminals. If you later need to re-install FU.COM to this terminal, you can do that by choosing it from the list. Send an initialization string to the terminal? If you want to initialize your terminal when FU.COM starts (e.g. to download commands to programmable function keys), you answer Y for yes to this question. If not, just hit RETURN. If you answer Y, you may choose between entering the command directly or defining a file name containing the command string. The latter is a good idea if the initialization string is long. Send a reset string to the terminal? Here, you may define a string to be sent to the terminal when FU.COM terminates. The description of the initialization command above applies here. CURSOR LEAD-IN command: Cursor Lead-in is a special sequence of characters which tells your terminal that the following characters are an address on the screen on which the cursor should be placed. When you define this command, you are asked the following supplementary questions: CURSOR POSITIONING COMMAND to send between line and column: Some terminals need a command between the two numbers defining the row and column cursor address. CURSOR POSITIONING COMMAND to send after line and column: Some terminals need a command after the two numbers defining the row and column cursor address. Column first? Most terminals require the address of the format: first ROW, then COLUMN. If this is the case on your terminal, answer N. If your terminal wants COLUMN first, then ROW, then answer Y. page 4 of 5 OFFSET to add to LINE Enter the number to add to the LINE (ROW) address. OFFSET to add to COLUMN Enter the number to add to the COLUMN address. Binary address? Most terminals need the cursor address sent in binary form. If that is true for your terminal, enter Y. If your terminal expects the cursor address as ASCII digits, enter N. If so, you are asked the supplementary question: 2 or 3 ASCII digits? Enter the number of digits in the cursor address for your terminal. CLEAR SCREEN command: Enter the command that will clear the entire contents of your screen, both foreground and background, if applicable. Does CLEAR SCREEN also HOME cursor? This is normally the case; if it is not so on your terminal, enter N, and define the cursor HOME command. DELETE LINE command: Enter the command that deletes the entire line at the cursor position. INSERT LINE command: Enter the command that inserts a line at the cursor position. ERASE TO END OF LINE command: Enter the command that erases the line at the cursor position from the cursor position through the right end of the line. START OF 'HIGH-LIGHTING' command: If your terminal supports high-lighting (inverse video, underline, etc.), then define the command that initiates the high-lighting. If this command is defined, the following question is asked: page 5 of 5 END OF HIGH-LIGHTING command: Define the command that cancels high-lighting and sets the screen to show characters in 'normal' video. Number of rows (lines) on your screen: Enter the number of horizontal lines on your screen. Number of columns on your screen: Enter the number of vertical column positions on your screen. Delay after CURSOR ADDRESS (0-255 ms): Delay after CLEAR, DELETE, and INSERT (0-255 ms): Delay after ERASE TO END OF LINE and HIGHLIGHT On/Off (0-255 ms): Enter the delay in milliseconds required after the functions specified. RETURN means 0 (no delay). Is this definition correct? If you have made any errors in the definitions, enter N. You will then return to the terminal selection menu. The installation data you have just entered will be included in the installation data file and appear on the terminal selection menu, but installation will not be performed. When you enter Y in response to this question, you are asked: Operating frequency of your microprocessor in MHz (for delays): As the delays specified earlier are depending on the operating frequency of your CPU, you must define this value. The installation is finished, installation data is written to FU.COM, and you return to the outer menu. New installation data is also saved in the installation data file and the new terminal will appear on the terminal selection list when you run FUINSTAL.DOC in future.
