This is ChangeLog Thu Mar 27 08:13:33 EST 2003 rxtx-2.1 and rxtx-2.0 changes are kept in the same file. skip to the version you downloaded. 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. 2.1-7pre15a build without requiring rxtxZystem.dll. Add back the TIOCGICOUNT #define for breaks. 2.1-7pre15 100 fold speedup of read(byte) and read(byte[] ...) 10 fold speedup of available() implementented read(byte[],offset,length,terminator[2]); -- not tested. 2.1-7pre14 select fix that could cause crashes in read and the eventLoop -- 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() 2.1-7pre13 Isolated lockup on w32 read. Added possible fix for w32 write lockups throw error on impossible write situations. - small input buffer, large writes. 2.1-7pre12 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. 2.1-7pre11 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 2.1-7pre10 wrote Zystem (probably will be a seperate library) for logging over the network. Some attempts to fix lockup bugs. -pedantic compile passes. 2.1-7pre9 termios.c cleanup (w32) 2.1-7pre8 More LPT support for w32 2.1-7pre7 initial LPT support for w32 2.1-7pre6 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. 2.1-7pre5 Later stage tinkering with flowcontrol and parity fixes. Possibly bugs (w32 has many ways this can be setup). 2.1-7pre4 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 -- 2.1-7pre3 fixed //./COM?? so matlab can do s=serial('COM16') -- needed to test tcrash.m 2.1-7pre2 support for COM1-16 on w32 using //./COM?? 2.1-7pre1 Mark/Space parity fixes on w332 2.1-6 Solaris Enumeration fixes 2.1-6 Sep 7, 2002 read(byte) does not timeout read(byte[]) returns 0 on timeout (Fixes DalSemi iButtons) Dave Dribin QNX Port Bill Smith read() fixes - should be the same as Sun's CommAPI now. timout and threshold fixes for above Bill Smith All QA tests passed.

Makefile.am 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. Makefile.am - 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 - sheldon_young@yahoo.com) Commented SerialImp.c (taj@www.linux.org.uk) 1.2pre4 Aug 12, 1998 The CommAPI has changed in the newest beta from Sun, now named "javacomm20-ea".
