+ * monitor.c: make_xmodem_packet and print_xmodem_packet go away.
+ send_xmodem_packet shows up to do the obvious. Lots of fixes to
+ xmodem downloads including resetting of block number at start of
+ new transfers, fix for buffer overrun problem, addition of CRC
+ generation code.
+ * (monitor_open): loadtype_str and loadproto_str now default to
+ first entry in monitor_ops->loadtypes.
+ * (monitor_wait): Lengthen register dump buf, because of verbose
+ Winbond monitor.
+ * (monitor_fetch_register): Report unimplemented registers as 0.
+ * (monitor_read_memory): Only do 16 byte aligned transfers
+ because of formatting weirdness with the Winbond monitor. Also,
+ ignore non-hex, non-whitespace formatting between bytes (same
+ monitor).
+ * (monitor_load): Clean up logic.
+ * (monitor_load_srec): Re-do xmodem support. Move lots of it
+ into send_xmodem_packet.
+ * (getacknak): Get rid of polls and timeouts. Handle CRC
+ requests from receiver.
+ * (monitor_make_srec): Efficiency improvements. Don't call
+ sprintf to output two digit hex numbers.
+ * (crcinit, docrc): New, CRC-16 support routines.
+ * (send_xmodem_packet): New routine to generate either CRC-16 or
+ checksummed xmodem packets.
+
+ * remote-est.c (est_loadtypes), rom68k-rom.c (rom68k_loadtypes):
+ Reduce tables down to only the load types supported by each
+ monitor.
+
+ * w89k-rom.c (w89k_supply_register): Parses output of Winbond
+ register dumps.
+ * (w89k_loadtypes, w89k_loadprotos): Reduce to just srec/xmodem.
+ * (w89k_cmds): Add clear all breakpoints, memory fill, and dump
+ registers commands.
