/* By the power of binutils and the one true editor, here is a compacted
   form of the ll_init_COUNTRY settings from ltmodem.sys.

   Copyright (C) 1999 Jamie Lokier.

   These parameters are extracted from ltmodem.sys, by examining the
   disassembly of each ll_init_<country> function.  The script
   xcountry.pl was used, so the country_init_<country> arrays are reliable.

   country_init_base was extracted from x_init_international.  There was
   no ll_init_twn function: I created it to match the effect in
   x_init_international for Taiwan.

   The `countries' array was generated with lots of keyboard macros after
   reconstructing the code in ltmodem.sys's x_init_international.  I'm
   fairly sure it is correct.  There are some strange rules in that code.
   My version of x_init_international is quite different, but should
   have the same effect. */
