  The values are generic, rather than specific to UNIX.  We can't use B75,

  necessarily have these symbols defined.  The BPS_xxx symbols are
  Kermit-specific, and are defined in ckcdeb.h or on the CC command line.

    2. The default might be a filename, a directory name, a relative
       pathname, or an absolute pathname.  This routine must convert it into
       into a fully qualified (absolute) pathname so the user knows exactly
       where the file is to be found or stored.  In addition, the Windows
       version of this routine must separate the directory part from the
       name part, so it can display the given directory in the file dialog,
       and put name in the filename box to be edited, replaced, or
       accepted.

    3. When called with FC 4, the Windows version should include "New" and
       "Append" buttons in the dialog. so the user can say whether the file
       should overwrite any file of the same name, or be appended to it.

  DEC-20, even when you TELNET to it, is sensitive to Ctrl-O and Ctrl-T.
  If you tell C-Kermit to SET CONTROL PREFIX 15 and/or 20, it doesn't help
  because CLEAR-CHANNEL is still in effect.  If the user goes to the trouble
  to set up some prefixing, then Kermit should do what the user said.  In
