Not all ZDX modems support 2D encoding.  Models more than a year or two
old probably do not.  Check by issuing this query:

AT+FDCC=?

The response from a newer model (firmware rev 2.13A or 3.13A) will be

+FDCC=(0-1),(0-5),(0-4),(0-2),(0-2),(0),(0),(0-7)
                                ^
The fifth item                  |
is the encoding capability of the modem.  If this value is '(0)', your
modem only supports 1D encoding.

MultiTech upgraded my modem's firmware for free - give their tech
support line a call.
