+ChangeLog for the UTS Global 3270-support patch
+Sep 2002: Get bootup colors right on 3270 console
+ * In tubttybld.c, substantially revise ESC processing so that
+ ESC sequences (especially coloring ones) and the strings
+ they affect work as right as 3270 can get them. Also, set
+ screen height to omit the two rows used for input area, in
+ tty3270_open() in tubtty.c.
+Sep 2002: Dynamically get 3270 input buffer
+ * Oversize 3270 screen widths may exceed GEOM_MAXINPLEN columns,
+ so get input-area buffer dynamically when sizing the device in
+ tubmakemin() in tuball.c (if it's the console) or tty3270_open()
+ in tubtty.c (if needed). Change tubp->tty_input to be a
+ pointer rather than an array, in tubio.h.
+Sep 2002: Fix tubfs kmalloc()s
+ * Do read and write lengths correctly in fs3270_read()
+ and fs3270_write(), whilst never asking kmalloc()
+ for more than 0x800 bytes. Affects tubfs.c and tubio.h.
+Sep 2002: Recognize 3270 control unit type 3174
+ * Recognize control-unit type 0x3174 as well as 0x327?.
+ The IBM 2047 device emulates a 3174 control unit.
+ Modularize control-unit recognition in tuball.c by
+ adding and invoking new tub3270_is_ours().
+Apr 2002: Fix 3270 console reboot loop
+ * (Belated log entry) Fixed reboot loop if 3270 console,
+ in tubtty.c:ttu3270_bh().
+Feb 6, 2001:
+ * This changelog is new
+ * tub3270 now supports 3270 console:
+ Specify y for CONFIG_3270 and y for CONFIG_3270_CONSOLE.
+ Support for 3215 will not appear if 3270 console support
+ is chosen.
+ NOTE: The default is 3270 console support, NOT 3215.
+ * the components are remodularized: added source modules are
+ tubttybld.c and tubttyscl.c, for screen-building code and
+ scroll-timeout code.
+ * tub3270 source for this (2.4.0) version is #ifdeffed to
+ build with both 2.4.0 and 18.104.22.168.
+ * color support and minimal other ESC-sequence support is added.
