src/winsup/cygwin ChangeLog fhandler_serial.cc ...


CVSROOT:	/cvs/src
Module name:	src
Changes by:	cgf@sourceware.org	2003-02-01 04:48:03

Modified files:
	winsup/cygwin  : ChangeLog fhandler_serial.cc termios.cc 

Log message:
	* fhandler_serial.cc (fhandler_serial::open): Avoid extraneous setting of res.
	* termios.cc (tcsetattr): Correctly record errno after tcsetattr call.
	* fhandler_serial.cc (fhandler_serial::tcsetattr): Add error-checking so that
	if any Win32 SetComm*() calls fail, errno gets set to EINVAL and tcsetattr()
	returns -1.  Catch invalid bitrates, mostly.  If baud rate setting is B0, just
	drop DTR and leave Win32 DCB bitrate as-is since 0 is not a valid Win32
	setting.
	(fhandler_serial::tcgetattr): If DTR is low, populate the bitrate as B0,
	otherwise get it from the DCB.
