+
+tty.c, file.h, xbios.c: ++entropy@terminator.rs.itd.umich.edu
+
+	Add a real TIOCSETP (differs from TIOCSETN in that it waits for
+
+	the output buffer to be empty if the device supports TIOCOUTQ.)
+
+	Remove a kludge in rsconf() which is not needed if a real TIOCSETP
+
+	exists.
+
+various places: ++schwab@issan.informatik.uni-dortmund.de
+

+	of bytes available for reading, even if there
+
+	are no writers.
+
+tosfs.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Make FIONREAD return an accurate count of the
+
+	number of bytes left to read.
+
+tty.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Fcntl(TIOCSETP) now puts the terminal into RAW or
+
+	cooked mode immediately (it used to take until
+
+	the next read or write).
+
+dosfile.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Watch out for aliasing of pointers passed to
+
+	Fselect().
+
+
+
+version 1.10

+
+	Fixed ioctl(,,TCSETBAUD) when oldbaud == newbaud.
+
+dosdir.c,unifs.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Extended Dfree() to work properly on arbitrary drives,
+
+	not just ones that are root directories or aliased
+
+	(this arises e.g. for Dfree() on U:, when the current directory
+
+	isn't a root).
+
+syscall.spp,inline.h: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Bugfix for TOS 1.4: the BIOS expects register A5 to
+
+	contain a 0 when it is called.
+
+bios.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Make reads on console interrupt driven.
+
+procfs.c,shmfs.c:
+
+	Fixed Fseek(offset,f,2) to properly add "offset" to the
+
+	end of file position, rather than subtracting it.

+
+	ownership, access modes, and time stamps. Restricted
+
+	Dcntl on u:\dev to superuser processes.
+
+biosfs.c, pipefs.c, file.h: ++entropy@terminator.rs.itd.umich.edu
+
+	Fix TIOCFLUSH on biosfs.
+
+	Give meaning to TIOCFLUSH's argument:  it is now a pointer
+
+		to a longword mask specifying the type of flush:
+
+		*arg & 1 -> flush input only
+
+		*arg & 2 -> flush output only
+
+		*arg == 0 -> flush input and output
+
+		arg == NULL -> flush input and output (backwards compatibility)
+
+	Add TIOCOUTQ to biosfs and pipefs.  The argument is a pointer
+
+		to a longword to be filled with the number of bytes in the
+
+		output buffer.
+
+*fs.c,file.h:
+
+	Added an "rdev" field to the XATTR structure, so that programs
+
+	can find the BIOS device number for character devices.
+
+biosfs.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Added a /dev/fd subdirectory.
+
+biosfs.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Restrict some operations to privileged users.

+filesys.c: ++itschere@TechFak.Uni-Bielefeld.de
+
+	Create new device filenames in lower case, for consistency.
+
+dosdir.c,tosfs.c: ++itschere@TechFak.Uni-Bielefeld.de
+
+	Improved security for Fdelete, Dsetpath, and some other
+
+	calls; made TOS file systems accessible only to root and
+
+	the admin group.
+
+bios.c,syscall.spp,main.c,proc.h:
+
+	Added a flag (in_dos) to the PROC structure; the BIOS can use
+
+	this for security checking on Rwabs and similar calls.
+
+procfs.c: ++micro@imada.ou.dk
+
+	Bug fix: memory protection modes weren't being properly reset
+
+	after memory was read from/written to.
+
+mem.c: ++bernd.kischnik@cdc2.ifum.maschinebau.uni-hannover.d400.de
+
+	Fixed a bug with memory initialization when the screen is
+
+	at a fixed location (i.e. with 3rd party graphics cards).
+
+context.spp: ++alex@falcon.demon.co.uk
+
+	Only check for 64 bytes of supervisor stack, rather than 1K; also,
+
+	corrected some loop counters.
+
+tty.c: ++nox@jelal.north.de
+
+	Hack so that ^S/^Q work on BIOS devices other than the keyboard.
+
+intr.spp: ++nox@jelal.north.de
+
+	Check for auto-repeating keys so that Fselect() wakes up more
+
+	quickly.
+
+bios.c: ++nox@jelal.north.de
+
+	Made BIOS devices take less CPU time while waiting for characters.
+
+filesys.c:
+
+	If a search for a path component (other than the last one)
+
+	fails, always return EPTHNF (like GEMDOS does).
+
+pipefs.c:
+
+	When freeing a closed fifo, free any associated tty as well.
+
+main.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	New command for mint.cnf: "include".
+
+mem.c:
+
+	In create_base(), limited the amount of memory assigned to
+
+	a new basepage if the current process has a limit assigned
+
+	by Psetlimit().
+
+biosfs.c:
+
+	Fixed the DEV_NEWBIOS call (it wasn't linking the newly created
+
+	device into the bios file system chain).
+
+dosdir.c:
+
+	Based on a suggestion by Uwe Seimet: made Dlock() return
+
+	ELOCKED when called twice by the same process, so that under
+
+	single tasking AES accessories may use it.
+
+unifs.c:
+
+	Fixed a bug in FS_UNMOUNT (fc->index is not necessarily
+
+	a pointer to a UNIFILE, since the file system may use
+
+	that for its own purposes).
+
+debug.c: ++nox@jelal.north.de
+
+	Make only ctrl-alt-key characters significant to the
+
+	debug code (before, any character could start/stop output).
+
+memprot.c,mem.c,dosmem.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Andreas did a major clean-up of the memory protection code.
+
+	It's now faster, and quite a few bugs have been fixed.
+
+mem.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Made sure that only even addresses are passed to zero() (I guess
+
+	some linkers don't make sure that text, data, and bss are all
+
+	even lengths?)
+
+util.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	In kmalloc(), the size passed to nalloc_add_arena() was wrong.
+
+main.c,debug.c,mem.c: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Restore the screen to its original address when exiting MiNT.
+
+fasttext.c: ++nox@jelal.north.de
+
+	Allowed the fasttext device to be opened more than once.
+
+nalloc2.c: ++nox@jelal.north.de
+
+	Fixed the code for figuring out when to free an arena (it didn't
+
+	use to take account of the arena size itself).
+
+proc.c: ++Martin_Koehling@un.maus.ruhr.de
+
+	Allocate all memory before doing file duplication, so that
+
+	if a fork() runs out of memory we don't leave cookies
+
+	hanging.
+
+main.c: ++brad@tazboy.jpl.nasa.gov
+
+	Allow quotes to delimit arguments in the MINT.CNF file.
+
+xbios.c:
+
+	Installed a work-around in dosound() for Pure C's problem
+
+	with "volatile".
+
+filesys.c:
+
+	Put in a temporary kludge so that .XFSes that don't install
+
+	BIOS vectors can work (for a while). Note that .XFSes should
+
+	either install BIOS vectors, or should mount themselves on
+
+	drive U: without taking up a drive letter. THIS KLUDGE WILL
+
+	GO AWAY SOMEDAY SOON!!!
+
+syscall.spp: ++schwab@ls5.informatik.uni-dortmund.de
+
+	Various optimizations.
+
+
+
+version 1.09
+
+
+
+biosfs.c:
+
+	Implement file locking for BIOS devices.
+
+dosmem.c:
+
+	Fix the Pexec(200,...) bug (trying to save the command line
+
+	image must be done *before* the existing program's memory
+
+	is freed).
+
+nalloc2.c,util.c:
+
+	Allow kmalloc()'d memory to be returned to the OS, if possible.
+
+xbios.c:
+
+	Dosound() can be called with a negative number as its parameter,
+
+	in which case it is only an inquiry function.
+
+
+
 version 1.08
