Simon> Where is there some documentation on handlers ??

There is some documentation on the packet system in the AmgiaDOS
Technical Manual (Bantam Books) and a sample handler...  in BCPL.
(ugh.)  This documentation is rather poor in that it doesn't tell you
much of what you need to know to write a proper handler in C or
assembly.  Apparently the Software Distillery (Walker, et al) have
some good example handler code that may be worth getting a hold of.
(I've been intending to, but haven't gotten around to it...  Doug, if
you're reading this, could you Email me the info you guys have on
handlers to deven@rpi.edu?  Thanks...)

You could also look at the NULL: source, which is okay, but doesn't DO
much...  Dillon's nfs-handler for DNet is another possible example,
but Dillon's code tends to be written in a rather difficult-to-read
fashion, so caution may be in order.  That's all the sources that leap
to mind.

The RKM's are absolutely essential reference materials, but
unfortunately, they have virtually no information on AmigaDOS.  Check
the include files <libraries/dos.h>, <libraries/dosextens.h> and
<libraries/filehandler.h> for what little extra information you can
glean from the data structures defined and the comments accompanying
them...  [these should be in the includes section of the 1.3 Includes
and Autodocs RKM, as well as on your compiler disks.]

AUX: is pretty dumb, but I would advise anyone using AUX: to run a CLI
on a terminal to get ConMan 1.3 by Bill Hawes, (Shareware product,
widely available) and try its CNX: handler.  It allows you to use a
"console" over any exec device.  Or at least, you can attempt to.  (I
wouldn't suggest trying to use CNX:trackdisk.device!)

Anyway, if you use "CNX:serial.device", [as in the command "NewCLI
CNX:serial.device"] you will get an effect similar to AUX:, except
that you get ConMan's input editing as a bonus.  For anyone not
familiar with ConMan, the input editing is similar to that of C-A's
NEWCON: handler, except that it is far more flexible and powerful than
the C-A handler, and I think it may even be smaller.  [or I could be
thinking of ASH, the ARP shell, compared to AmigaShell -- ASH is
smaller and much better...]

ConMan 1.3 is well worth getting simply for the Amiga console
enhancements, but if you're using AUX: now, it is doubly invaluable
for CNX:...  [by the way, the "serial.device" part of the CNX:
"filename" is almost certainly case sensitive.  That is, you can use
"cnx:serial.device", but "CNX:SERIAL.DEVICE" is probably right out.]

I don't know if CNX: does the sort of mapping you're looking for, but
take a look at it first; it may.
