I could really use examples of handlers for the software trap vectors.  Let's
just say that the documentation I have available isn't entirely clear or
consistent.  Specifically, if anyone would care to post fragments in C or
assembler that did the following 2 functions, I probably wouldn't be the
only person grateful to see them:

1) Attempts to read from a floppy disk.  If there is no disk in the drive,
   writes a message to the screen and waits for a keypress, then retries the
   original read (etc until satisfied).  The built-in 'drive not responding'
   alert is never activated.
2) Accepts input into a string with Cconrs  (do I have the name right?  I
   never remember such things, and my manuals are elsewhere).  If control
   C is pressed it intercepts the terminate vector and does something
   sensible (like clearing the input string and starting over).

Thanks.
