- OS-9/68K BACKGROUND
-
- OS-9/68k is a multiuser, multitasking operating system designed to run on
- all Motorola 680x0 family processors from Microware Systems Corporation, 1900
- N.W. 114th Street, Des Moines, Iowa 50332 (Trademarks: Microware, OS-9,
- OS-9/68000, OS-9000).
-
- Due to its modular design, most of the code is completely hardware
- independent, so it can be easily be ported to a different hardware by writing
- new device drivers.
-
- The original (1980) OS-9/6809 was designed for the Motorola 6809 processor.
- Later (1983) they switched to the 680x0 family and released OS-9/68000. For
- speed and compactness reasons most of the OS-9/68000 kernel is written in
- 680x0 assembler language. Now there is a so-called OS-9000 by Microware. Its
- kernel is written in C and thus it is portable. It is presently available for
- 680x0 and Intel's 80386/486, and Microware plans to add further support for
- RISC and CISC processors. (C-Kermit has not yet been tested under OS-9000.)
-
- The 100% ROM-able, fast, compact code in conjunction with real-time
- capabilities make OS-9/68k ideal for ROM-based systems used in measuring,
- controlling, etc. It has found a wide acceptance within the scientific and
- industrial world.
-
- Yet, a full disk based OS-9/68k offers a program development environment
- similar to UNIX. This includes (of course, limited) UNIX sofware compatibility
- at C source code level, source code level debugging, UNIX I/O model, UNIX task
- model, UNIX-like shell and networking.
-
- A number of UNIX utilities like lex, yacc, lint, etc, have been ported to
- OS-9/68k.
-
- The basic commands of OS-9 are:
-
- DEL delete a file
- DELDIR delete a directory
- MAKDIR create a directory
- DIR directory listing
- PROCS show currently running processes
- LIST type contents of a text file
- CWD change working directory
- PD print working directory
-
- All commands can be given a "-?" as a switch, which will display a brief
- (usually sufficient) help message.
-
- All command references (like all references to names on OS-9/68k) are NOT
- case sensitive (switches, though, may be case sensitive since they are
- interpreted by the running program).
-
- On OS-9 systems you can redirect stdin, stdout, stderr just like in UNIX,
- and you can run programs (including Kermit) in the background.
- Pipelines work just like in UNIX.
-
- OS-9 doesn't know anything about character sets; all messages are in English
- using ascii.
-
- OS-9 does not generally have windows etc. (windows has been ported by someone,
- though). You can't really say anything about the terminal emulation.
- Many systems don't even have a console, but only RS232 lines, with no
- action by th driver whatsoever. So it depends on the terminal conncted to
- that line.
- In case a display is already part of the machine, then it depends on the
- vendor (which usually also does the portation), which emulation the console
- will have. E.g. I have ported OS-9 to Atari, which includes a VT52 emulation
- on the console.
- OS-9 is really meant to be ported, so no restrictions are given.
-
-
-
- OS-9/68K DEVICES
-
- All devices (terminal lines, networks, disks) can have arbitrary names but
- the usual convention is:
-
- Terminal lines:
- term the console terminal
- t1 terminal line #1
- :
- tn terminal line #n
-
- Harddisks:
- h0 hard disk #0
- h1 hard disk #1
- :
- hn harddisk #n
-
- Floppy disks (diskettes):
- d0 floppy disk drive #0
- d1 floppy disk drive #1
- :
- d0 floppy disk drive #n
-
- A path name starting with a slash ("/") must always include a device name
- as the first field. For example, the C-Kermit command SET LINE /T3 would
- select the terminal line /t3.
-
- The console terminal is either a real terminal, or the screen and keyboard of
- a workstation such as a Macintosh, Amiga, or Atari ST that is running OS-9.
- Terminal emulation is not done by OS-9 C-Kermit, but rather by the real
- terminal or the workstation console driver. This includes the capability to
- display national and international characters.
-
-
- THE OS-9/68K FILE SYSTEM
-
- The file system is tree-structured just like the UNIX file system.
-
- /h0/chris
-
- means the directory or file "chris" on hard disk #0.
-
- chris/rubbish
-
- means the subdirectory or file "rubbish" in the subdirectory "chris" of the
- current directory.
-
- The command "chd" without any parameters will always take you to your home
- directory.
-
- Wildcard expansion is performed by the shell with two metacharacters:
-
- * stands for an arbitrary string of arbitrary length
- ? denotes a single character
-
- C-Kermit/OS-9 also expands wildcards itself, using the same notation, for
- example:
-
- C-Kermit>send ck*.\?
-
- (Note: the question mark must be prefixed by "\" to override its normal
- function of giving a help message.)
-
- OS-9/68k files are sequential streams of 8-bit bytes, just like in UNIX,
- except that carriage return (CR, ASCII 13) is the line terminator, rather than
- linefeed (LF, ASCII 10). Binary files are simply streams of arbitrary 8-bit
- bytes. The OS-9 operating system and utilities are "8-bit clean", so text
- files can use any ASCII-based character set that is compatible with your
- display and data entry devices, for example ISO 8859-1 Latin Alphabet 1.
-
- Unlike UNIX, OS-9/68k has a built-in method to gain exclusive access to
- devices, so no lock files are needed. The user will be told if the device is
- already in use.
-
-
- TO BUILD C-KERMIT FOR OS-9:
-
- Collect all the C-Kermit source files into a directory:
-
- ckc*.c, ckc*.h, cku*.c, cku*.h, ckwart.c, ckcpro.w, ck9*.*
-
- There are two makefiles: ck9ker.mak and ck9ker.gcc. If you have a running
- version of the GNU C compiler, use ck9ker.gcc (it produces smaller, more
- efficient code); otherwise use ck9ker.mak which uses the standard OS-9/68k C
- compiler. Read the appropropriate makefile, edit the necessary changes
- mentioned there, create the subdirectories, and make the new Kermit by typing:
-
- make -f=ck9ker.mak
-
- or:
-
- make -f=ck9ker.gcc
-
- Read the "beware file" ck9ker.bwr for hints relating to the OS-9 terminal
- driver.
-
-
- USING OS-9 C-KERMIT
-
- The commands and operation of OS-9 C-Kermit should be identical to those of
- UNIX C-Kermit, with the exceptions noted above and in the "beware file". The
- user documentation for C-Kermit is:

- Burlington, MA, 1993, approx. 500 pages.
