2.1-7pre17 Oct 17, 2003
merged with 2.0 and took small changes from cvs.
2.1-7pre16 Mar 27, 2003
remove debug "Condition" warnings used to debug NT4 issues.
build without requiring rxtxZystem.dll. Add back the
TIOCGICOUNT #define for breaks.
100 fold speedup of read(byte) and read(byte[] ...)
10 fold speedup of available()
implementented read(byte[],offset,length,terminator[2]);
-- not tested.
select fix that could cause crashes in read and the
-- cleaner patch is pending but not tested as
mentioned to Melissa and Jauhar.
Tried to cause exceptions for possible NT4SP6 writes
-- this was the "Three Blind Mice" test
Changed build tool chain for XP problems (?).
-- "XP Blows up"
Support for COM1-256
port reenumeration for people that change win32
port assignments CommPortIdentifier:getPortIdentifiers()
Isolated lockup on w32 read.
Added possible fix for w32 write lockups
throw error on impossible write situations.
- small input buffer, large writes.
All input stream methods are synchronized now.
I had this in before cleaning up but thought it
was not needed (nothing failed here).
read() will toss an IOException (caught in the
examples below but not in this library) if read
thinks there will be a deadlock.
Some small fixes found while merging with rxtx 2.0
for public release. Just sanity checks for library
versions and such.
- everything is in synch with the public CVS and
public prerelease bins are out and being tested.
fix for lockup found.
removed Python and Cygwin code (ZystemImp.c)
removed extra attempts to fix lockup
removed previous attempts to fix tcrash
- the solution before was to avoid using the
API but now it appears to work with it -crazy
wrote Zystem (probably will be a seperate
library) for logging over the network. Some
attempts to fix lockup bugs.
-pedantic compile passes.
termios.c cleanup (w32)
More LPT support for w32
initial LPT support for w32
tlockup.m does not lock but fails (?) (W2K SP2)
tcrash.m does not crash (W2K SP2)
suite serial passes (W2K SP2)
debug for flow control and parity switched off.
Later stage tinkering with flowcontrol and parity
fixes. Possibly bugs (w32 has many ways this can
be setup).
testRead() now uses //./COM9 to verify port is
usable (fixes bug introduced in pre3)
build used java/jar/javac 1.3.1_06-b01
-- initial tinkering with parity --
fixed //./COM?? so matlab can do s=serial('COM16')
-- needed to test tcrash.m
support for COM1-16 on w32 using //./COM??
Mark/Space parity fixes on w332

Yeun-Ping Leung contributed Free-BSD support
1.2pre7 Oct 14, 1998 Various Fixes
1.2pre6 Oct 6, 1998 cleaned up documentation. Pulled out win32 support. remove full path from JAR command.
1.2pre5 Aug 12, 1998 Added David Atkinson's support for which implements event
notification, hardware flow control (tested with a modem),
multiple bytes reads etc. Needs to be converted back to
termios calls. Claims to work with blackbox.
.cvsignore - Added to ignore generated files such as
"config.h". It just cleans up CVS reports of what's new
and different. - Add a "jcl.jar" target to make a JAR file
for JCL.
SerialImp.c - Implemented SerialInputStream_skip(). If
it runs out of memory it uses a slower algorithm which
uses almost no memory.
- Support for baud rates of 38400. - Rename get_speed to
bps2speed_t (bits-per-second to speed_t constant) to
remove ambiguity.
- The GetSpeed functions now correctly return the bps
speed rather than the speed_t constant. This means JCL
will now return the correct speed.
- Add speed_t2bps to be the reverse of bps2speed_t.
- Fix the spelling of "receive".
Added /dev/modem to the list of ports because it's very
common. Added comments from Suns NullDriver sample,
giving credit where necessary. (Sheldon Young -
Commented SerialImp.c (
1.2pre4 Aug 12, 1998 The CommAPI has changed in the newest beta from Sun,
now named "javacomm20-ea". I have attached,
which I have modified so it now compiles.
