Well, I've got the Lib & Dev RKM (granted it's not the latest version) and 
they give absolutely _NO_ info on how to make AmigaDOS device handlers.  It
does cover Exec devices (sort of).

There is some scant documentation on AmigaDOS handlers in Bantam's AmigaDOS
Technical Reference Manual.  3.8.1 gives the packet formats for the various
commands and a faily useless BCPL skeleton handler starting on page 293 in
my edition.

There are some better examples in C  floating around (Like Matt Dillon's and
CBM's).  I'll be happy to send these to anyone interested.

I'm working on a SCRIPT: handler using a second process similar to Dillon's
debugging process and it's crashing badly.  I'd appreciate hearing from anyone
out there that really understands how to write handlers.
