+1999-04-14  Bart Veer  <bartv@cygnus.co.uk>

+1999-04-09  Gary Thomas  <gthomas@cygnus.co.uk>
+

+
+1999-04-09  Jesper Skov  <jskov@cygnus.co.uk>
+
+	* src/common/tty.c: 
+	* include/pkgconf/io_serial.h:

+	when enabling xmit interrupts.
+
+1999-03-26  Gary Thomas  <gthomas@cygnus.co.uk>
+
+	* src/sparclite/sleb_sdtr.c: Change how the port is set up.  The transmitter
+	is now always enabled, just the interrupts are masked/unmasked to control it.
+	This lets the serial driver cooperate with Cygmon on the port used for GDB.
+	Note that currently serial input does not work for CON1 since Cygmon is
+	taking all of the receive interrupts for itself.
+	(sleb_sdtr_tx_DSR): Need to keep track whether xmit interrupt should be
+ 	enabled - otherwise it can get enabled incorrectly and we get interrupted
+	to death!

+

+
+	* src/mn10300/mn10300_serial.c: Now initially mask TX interrupts
+	at initialization and unmask/remask in start/stop xmit
+	routines. This has no real effect on the hardware, but the
+	simulator does not implement the LCR_TXE bit properly, resulting
+	in spurious TX interrupts during diagnostic output.
+	This was the cause of the slow output reported in PR 19559.
+
+1999-03-23  Gary Thomas  <gthomas@cygnus.co.uk>

+	configurations.
+
