    ... The receiver routine specified in the call to access_type().
    If some kind soul could enlighten me with a small code fragment I would be
    very thankful.

Our protocol stacks use a small ASM routine to save the registers and
switch to a stack of their own, and then call C to do the bulk of the
work.  You can probably use a compiler's "interrupt" function mechanism
to make it work, but you'll be relying on the driver leaving you enough
stack.  I don't have experience with Turbo's "interrupt" functions, and
while I know MSC can do them, I've never found the place in the manual
where they're explained.
    
    p.s.  What is the latest version of the Packet Driver Specification?

V1.09 is current.
