2004-04-22  Jani Monoses <[e-mail]>

	 * cdl/io_serial.cdl :
	 Invoke tail with stricter syntax that works in latest coreutils. 

2004-01-12  Dan Jakubiec <[e-mail]>

	* src/common/serial.c: serial_write() was returning an incorrect
	result code in non-blocking mode when output was blocked.  The
	previous code would return ENOERR with 0 bytes written.  This
	was fixed to return EAGAIN.

2003-08-18  Jay Foster <[e-mail]>

	* src/common/serial.c: Fixed bug for XON/XOFF flow control that
	would cause multiple XON (or XOFF) characters to be sent for a
	single flow control state transition.
	Fixed bug in serial_write() that would cause output data to be
	discarded if using polled mode with flow control, and output
	was blocked due to flow control.
	Fixed bug in serial_data_xmt_req() that would not stop sending
	data when output was flow controlled off (hardware flow control).

2003-09-02  Eric Doenges <[e-mail]>

	* src/common/tty.c: Make tty_select prototype match implementation.
	* src/common/termiostty.c: Make termios_select prototype match 
	implementation.

2003-09-02  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c: Make serial_select prototype match
	implementation.

2003-06-09  Nick Garnett  <[e-mail]>

	* src/common/serial.c: Changed all calls to cyg_drv_cond_signal()
	to cyg_drv_cond_broadcast(). Removed comment asking whether this
	matters: it does.

	* include/serialio.h: Added includes of pkgconf files so that the
	ifdefs in this file work properly.
	
	* include/serial.h: Added include of devtab.h to fix compile
	error.

2003-05-21  Gary Thomas  <[e-mail]> 	

	* src/common/serial.c (serial_get_config): Restart receiver 
	after input queue flush if it had been throttled.  Inspired
	by David Marqvar <[e-mail]>

2003-03-25  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c (serial_get_config): For both INPUT_FLUSH
	and OUTPUT_FLUSH keys, pass down to the hardware driver as well
	to allow it to flush FIFOs.
	Based on patch from Roland Cassebohm.

2003-03-20  Gary Thomas  <[e-mail]>

	* src/common/serial.c: Only return -EAGAIN if no data moved.

2003-03-11  Gary Thomas  <[e-mail]>

	* src/common/termiostty.c (termios_read): VMIN handling still wasn't
	quite correct.  When VMIN > 0, at least VMIN characters should be
	read.

2003-02-24  Jonathan Larmour  <[e-mail]>

	* cdl/io_serial.cdl: Fix doc link.

2003-02-14  Jonathan Larmour  <[e-mail]>

	* src/common/termiostty.c: Support VMIN > 0 properly.

2002-12-10  Gary Thomas  <[e-mail]>

	* src/common/tty.c (tty_write): Only return number of characters
	in original string which were written - don't include any CR/LF
	expansion characters.

2002-04-23  Jesper Skov  <[e-mail]>

	* tests/serial3.c (serial_test): Use 19200 baud rate when board
	cannot handle 38400.
	* tests/serial5.c (serial_test): Same.

2002-02-19  Jesper Skov  <[e-mail]>

	* cdl/io_serial.cdl: Removed termiostty.c build rule.

	* cdl/termios.cdl: Make termiostty.c building depending on actual
	requirements for its content.

2002-02-15  Jesper Skov  <[e-mail]>

	* tests/flow1.c: Also try DSR/DTR flow control (presently
	unsupported by Linux though).
	* tests/flow2.c: Same.

2002-01-11  Jonathan Larmour  <[e-mail]>

	* src/common/termiostty.c (termios_read): Don't return after VMIN,
	this was a stupid thing to do and decreases performance a lot.

2001-08-15  Gary Thomas  <[e-mail]>

	* tests/ser_test_protocol.inl: Change NONE in 'cyg_verbosity_level_t'
	to be _NONE [unused] to avoid name clash with <kernel/kapi.h>.

2000-12-08  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c: Fix CYGOPT_IO_SERIAL_FLOW_CONTROL_HW ->
	CYGOPT_IO_SERIAL_SUPPORT_LINE_STATUS typo when declaring callbacks
	Thanks to Brian Danilko for reporting.

2000-11-22  Jesper Skov  <[e-mail]>

	* src/common/serial.c: Changed #ifdef to #if used on an interface
	option.

2000-11-06  Jonathan Larmour  <[e-mail]>

	* src/common/tty.c (tty_write): Check buffer size appropriately
	since when doing \r\n expansion "size" may have been double
	incremented as a result.
	Thanks to Alex Mathews of Crosstor for the fix.

2000-10-20  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c: Include cyg/infra/cyg_ass.h for assertion
	support since we have assertions here!

2000-10-12  Jesper Skov  <[e-mail]>

	* tests/ser_test_protocol.inl: Moved most testing parameters into
	device driver CDL.

	* cdl/io_serial.cdl: Added comment.

2000-10-06  Jesper Skov  <[e-mail]>

	* src/common/serial.c (serial_rcv_char): Register overruns.
	
	* src/common/serial.c: Made block request functions return cause
	of failure. Necessary for the device driver to be able to
	fall-back to other transfer method efficiently.
	* include/serial.h: Added enum with failure types.

2000-10-03  Jesper Skov  <[e-mail]>

	* tests/ser_test_protocol.inl: Moved testing parameters to device

	non-default flow control config.

2000-09-27  Jesper Skov  <[e-mail]>

	* src/common/serial.c (serial_data_rcv_done,
	serial_data_xmt_done): Buffer pointers updated in _done instead of
	in _req to avoid race in xmt. Same change in rcv for consistency.
	* include/serial.h: Changed prototype accordingly.

2000-09-18  Jesper Skov  <[e-mail]>

	* cdl/io_serial.cdl: Added interfaces to allow test tweaking.

2000-09-06  Jesper Skov  <[e-mail]>

	* tests/ser_test_protocol.inl: Renamed some option names due to SH
	serial driver reorg.

2000-08-09  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c (serial_indicate_status): Treat flow control
	case conditionally

	flow control overall default off)

	* tests/flow1.c (cyg_start): Fix N_A_MSG -> NA_MSG typo
	* tests/flow2.c (cyg_start): Ditto

2000-08-03  Jonathan Larmour  <[e-mail]>

	* cdl/io_serial.cdl: Should default flow control to off

	* src/common/serial.c (serial_data_xmt_req): Update cbuf->nb
	(serial_data_rcv_req): Update cbuf->nb

2000-08-01  Jonathan Larmour  <[e-mail]>

	* cdl/io_serial.cdl: Add support for line status queries,
	software flow control, hardware flow control and POSIX termios
	* include/serial.h: Likewise. Also change prototype for set_config
	hardware operations to use keys to be more flexible.
	* include/serialio.h: Add lots of types and constants to support
	new line status and flow control config key queries
	
	* src/common/haldiag.c (haldiag_set_config): Use keys to be more
	flexible.

	* src/common/serial.c: Many changes to support software/hardware
	flow control (with low and high water points), line status and
	fix some omissions with select. Also fix bugs in block transfer
	functions resulting from EL/IX merge.

2000-06-19  Nick Garnett  <[e-mail]>

	* include/serial.h:
	* src/common/serial.c:
	Added nb field to cbuf_t structure. This keeps track of the number of
	bytes currently in the buffer. Without this counter, there is no
	way to distinguish a totally full buffer from one that is totally
	empty, since in both cases put==get.

2000-06-15  Nick Garnett  <[e-mail]>

	* include/serial.h: Added selinfo field to cbuf structure when
	select support is enabled.

	* src/common/serial.c:

	transfer interface.

2000-04-17  Hugo Tyson  <[e-mail]>

	* src/PKGconf.mak: remove; it's obsolete.

2000-04-13  Gary Thomas  <[e-mail]>

	* src/common/serial.c (serial_write): Make safer - only call
	'start_xmit' with DSRs disabled.

2000-04-11  Hugo Tyson  <[e-mail]>

	* cdl/io_serial.cdl (CYGPKG_IO_SERIAL_DEVICES): New package which
	is a container and control for the real device drivers.

2000-04-11  Jesper Skov  <[e-mail]>

	* cdl/io_serial.cdl: Bad hack to build separate test.
	* tests/serial_echo.c: Added.

2000-04-11  Hugo Tyson  <[e-mail]>

	* cdl/ser_.... (driver-specific cdl files):
	Remove all these; they are no longer needed following the change
	below.  They do exist in devs/serial/ARCH/PLATFORM/VERSION/cdl/
	directories various instead.

2000-04-07  Hugo Tyson  <[e-mail]>

	* ecos.db: Re-organize device packages.  This is a massive change
	involving deleting all the sources for serial and ethernet drivers
	from where they used to live in
	    packages/io/serial/current/src/ARCH/PLATFORM.[ch]
	    packages/net/drivers/eth/PLATFORM/current/src/...
	and reinstating them in
	    packages/devs/serial/ARCH/PLATFORM/current/src/...
	    packages/devs/eth/ARCH/PLATFORM/current/src/...

	All these new packages are properly defined in ecos.db, and are
	all of type "hardware" so that a "target" can grab them.
	
	This directory layout is descriptive of the devices we have right
	now, arch and platform are separate levels just to make it easier
	to navigate in the filesystem and similar to the HAL structure in
	the filesystem.

	It is *not* prescriptive of future work; for example, the mythical
	common highly-portable 16550 serial driver which works on many
	targets would be called "devs/serial/s16550/current", or a serial
	device for a particular board (cogent springs to mind) that can
	work with different CPUs fitted is "devs/serial/cogent/current".

	Changelogs have been preserved and replicated over all the new
	packages, so that no history is lost.
