Lessee ... &K3 is a semi-standard for setting the modems flow control
parameters. Perhaps it's different for the Zoom ... or perhaps it's not
supported at all with a 2400 bps modem. (Actually ... I thought you were
talking about a 9600bps modem).

You have the paddle board properly strapped for hardware handshaking. Since you
used Ded to modify the descriptor, understand that it's a _hex_ 80 even though
you would just type "xmode type=80". That's a 'feature' of xmode.

Now for cabling .... according to my cheat sheet:

        6                       6
        7                       4
        8                       5
        9                       22


Pin's 2 and 3 are transmit and receive. If this setup doesn't work, swap 'em on
one end. (I can never keep my DTE and DCE straight!)

Hope this helps.
