README.DOC News and corrections MS-DOS 3.20 1987-08-10 The contents of this file is an addendum to the previous TeleNova MS-DOS documentation for the COMPIS/SCANDIS computer. It replaces all previous README.DOC files.

Keyboard redefinitions (cf. KEYDEF) are preserved. Default is standard-mode and ANSI- mode. CTRL-X (not ESC) cancels the current input line. If no network is connected, the devices LPT1 and PRN are the parallel printer connected to J7 and the device AUX is serial communication on J2 (9600, none, 8, 1). Redirection and change of parameters is available with COM.SYS and MODE. System key combinations (Super)Shift+Ctrl+key are no longer affected by the state of the CapsLock-key. Single-drive systems emulates two flexible disk drives (A and B) with the available disk drive. MS-DOS will prompt for change of disk. ------------------------------------------------------------------------ COM.SYS An installable character device for extended serial communication (cf. MODE). No longer included in the default CONFIG.SYS. CPM Quick boot of CP/M-86 without memory reset. Useful with hard disk or network. CPMDIR/ The CP/M-86 flexible disk utility commands are now capable FROMCPM/ of handling disks with 8 or 9 sectors/track. An optional TOCPM last numeric argument specifies a CP/M user number. Default is user number 0. CS The change character set command can be used to change nationality of the character set also in PC-mode. The normal PC character set is number 0 and the Danish/Norwegian PC character set is number 1. In standard-mode the character set can also be specified in letters (cf. CP/M-86). DUMMY.SYS An installable dummy block device. Can be used to obtain the same device names (i.e. Z:) in different configurations. EMULATE EMULATE v3.0 is an enhanced version of the PC ROM BIOS emulator. Three levels of emulation are available. Level 1 corresponds to PC-mode. Level 2 is a slightly enhanced version of EMULATE v2.0. Level 3, in addition to level 2, supports direct handling of the video memory for the monochrome or color/graphics adaptors. This level of emulation requires 768K of RAM memory. Level 2 and 3 stays resident in memory when loaded. An optional parameter /1, /2 (default if 256K) or /3 (default if 768K) specifies the level of emulation. If level 2 or 3 is already loaded, the level of emulation can not be changed without resetting the computer. This must be done with the RESET button on the front of the computer. The different levels of emulation and other options are described in detail in the file EMULATE.DOC. NOTE! Use always the RESET button to restart the computer whenever the emulator is loaded! NOTE! EMULATE v3.0 may not be used together with PREMUL! FCOPY/ The general disk utility commands can prepare CP/M-86 and FPREP p-system flexible disks, and copy MS-DOS (not 40 tracks), CP/M-86 and p-system flexible disks. Refer to your CP/M-86 manuals for detailed information. FORMAT Single-sided flexible disks must be formated with parameter /1 (not /L). Parameter /4 (not /I) gives 40 tracks/side (PC format). For standard disk format in high density drive give parameter /9 (not /C). With parameter /C the disk directory is cleared. GETKEY A program for reading key value in batch files. The key value is available in the parameter ERRORLEVEL. HDISK Enhanced hard disk driver (cf. Hard Disk Manual). It replaces the driver in ROM BIOS version 3.02 (or later 3.0x) and stays resident in memory. HDISK sets the ERRORLEVEL 1 if "Driver is already loaded" or "Incorrect ROM BIOS version". KEYBxx The keyboard commands will activate the change immediately (no need to run STDMODE or PCMODE afterwards). The KEYBDA now gives a correct Danish (not Norwegian) keyboard layout and the new KEYBUS command gives an US English keyboard layout. The KEYBDA and KEYBUS commands loads a set of keyboard tables which replaces some of the keyboard tables resident in ROM BIOS. Only one keyboard program should be loaded after booting MS-DOS. The program remains resident in memory until you perform a system reset or power off the computer. If you load a second keyboard program, it will gain control of the keystrokes you type. However, the earlier program would still be in memory, and cannot be returned to. The KEYBDA and KEYBUS commands increase the resident size of MS-DOS in memory by approximately 1K bytes. The KEYBGR command gives a correct German keyboard layout only in PC-mode. NETPRINT Alternative print command that will take a filename as parameter. The file is output to the standard printer (local parallel or network printer). For network printers the spoolfile is automatically closed. PC print filter (cf. PREMUL) for all 7-bit printers or change of character set on C.Itoh 8510/1550 compatible printers is available. NETPRINT reads two additional parameters from MS-DOS. They can be assigned by the SET command. The parameter PRINTERCLASS specifies which of the 3 possible network printers to use (1, 2 or 3). Default is PRINTERCLASS=1. The parameter PRINTERMODE specifies print conversion or C.Itoh character set. The following options are available: 0 No conversion (default) PC PC to 7-bit character conversion JA, FR, US, UK, GE, SW, IT, SP, DN, NOR, NET, AF, FR2, or UK2 Change C.Itoh character set on printer If you put the line SET PRINTERMODE=PC into your AUTOEXEC.BAT file, you will get PC character conversion. NEWYEAR The IO.SYS file contains a default year, used for computers with old clock chips (COMPIS I and SCANDIS I). The NEWYEAR program updates this default year on the disk present in the default drive. NOVAED The full screen text editor uses the currently active character set (standard- or PC-mode). PBOOT Quick boot of p-System without memory reset (cf. Hard Disk Manual). Useful with hard disk or network. PREMUL The PC printer filter can be used for all 7-bit local parallel printers. It is possible to enable or disable the printer filter by supplying an optional parameter: /ON or /+ to enable, /OFF or /- to disable. The parameters /VER and /? display version number and filter status respectively. The printer filter is disabled during graphic screen dump. NOTE! PREMUL may not be used together with EMULATE v2.0 or later! RAM.SYS An installable block device for RAM disks. STDMODE Sets the standard COMPIS/SCANDIS keyboard codes and character set (cf. CP/M-86). Does not change the current ANSI/VT52 screen handling modes.
