+* Added workarounds for FTDI USB-serial adapters that feed previously
+  accumulated serial Rx bytes or outright garbage to newly started serial I/O

+  + fcup-atinterf back-end program for fcup-* does a sleep of 20 ms followed by
+    tcflush(target_fd, TCIFLUSH) on startup to flush any previously accumulated
+    serial Rx buffer garbage that would otherwise cause breakage.  The two
+    delays in the deep sleep wakeup logic (see doc/Deep-sleep-support) have been
+    reduced from 50 to 30 ms each, thus the total length of initial delays has
+    been reduced from 100 to 80 ms.
+
+  + In the rvinterf suite (see doc/Rvinterf-tools) a similar startup delay has
+    been added in the special corner case of a non-interactive one-shot
+    operation being commanded with rvinterf also being launched from the client
+    program with -p; see the "Startup synchronization hack" section in the new
+    Rvinterf-tools document.

 * fcup-smdump now restores the character set selection (AT+CSCS) setting on the
   target to the default "IRA" (ASCII) upon successful completion, after

 * A hack that was added in fc-host-tools-r5 solely to support one (1) defective

+* A number of documentation updates have been made: Deep-sleep-support and

+  long-overdue major updates, plus a number of minor updates as usual.

+  Slackware system for some reason has been fixed.
