	    Andrew Lunn <[e-mail]>
	
	* cdl/termios.cdl: 
	  src/common/termiostty.c: added Termios TTY channel #3
	* cdl/tty.cdl: 
	  src/common/tty.c: added TTY mode channel #3


2006-08-22  Peter Csordas <[e-mail]>

        * include/serialio.h (cyg_serial_baud_rate_t): Adding baud rate
	defines for 460800 and 921600 baud. 

2006-08-25  Gary Thomas  <[e-mail]>

	* cdl/io_serial.cdl:  Set parent for more intuitive ConfigTool layout.

2006-05-09  Andrew Lunn  <[e-mail]>

	* src/common/tty.c (tty_init): Fix compiler warning with
	diag_printf() arguments.

2005-09-02  Sebastien Couret <[e-mail]>

	* src/common/termiostty.c and 
	* tests/serial_echo.c : Fix compiler warning on a signedness 
	argument
	
2005-07-22  Andrew Lunn  <[e-mail]>

	* src/common/tty.c (tty_write): 
	* src/common/haldiag.c (haldiag_getc): Fixed pointer signness to
	avoid compiler warnings.
	* tests/*.c msglen should by an unsigned int to avoid compiler
	warnings.
	
2005-07-21  Andrew Lunn  <[e-mail]>

	* src/common/termiostty.c: Removed errbuf from priv. It was never
	being used after being allocated and never freed.

2005-06-27  Andrew Lunn <[e-mail]>

	* src/common/serial.c (serial_select): Swap the DSR locks and
	mutex locks around to avoid deadlocks with the rest of the code
	which uses this order.
	
2005-06-17  Andreas Gaer <[e-mail]>

	* src/common/serial.c (serial_select): Lock DSRs inside
	serial_select() as the serial DSR calls functions manipulating the
	cbuf structs, leading to a race condition. Also use the mutex to
	avoid races between different threads.

2005-05-13  Peter Korsgaard  <[e-mail]>

	* src/common/serial.c (serial_init): Fix compiler warnings about
	formats strings for diag_printf.	

2004-11-30  Jani Monoses <[e-mail]>

	 * cdl/io_serial.cdl : CYGPKG_IO_SERIAL_SELECT_SUPPORT requires 
	 CYGFUN_IO_FILEIO_SELECT specifically not just CYGPKG_FILEIO. The 
	 latter provides select support only in kernel configurations.
	 
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!

	* 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.

	* 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]>

	(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

	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

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.
