One difference between the AJ1259 and the RV 3451 is that the Vadic has
three switches on the front panel - the extra one is labelled "DA/VO/MA".
In the DA position, the modem is forced to connect to the line - apparently
the AJ has a "CONN" position of its "FA" (force answer) switch which performs
the identical function.  "VO" selects auto-answer mode, which is the AJ modem's
default anyway.  However, the "MA" (manual) position prevents the modem from
answering the phone at all, even if DTR is asserted - the AJ modem has no
equivalent capability.  Now, if you leave your terminal powered off, or have
some way of forcing it to drop DTR when you aren't using it, the modem
won't answer anway, so you have no problem.  This IS a difference between
the two, though.  I'm in the process of buying an AJ 1259 myself, and the
local distributor is apparently willing to modify them (for a small fee, of
course) to add a switch which will provide the unconditional disconnect
function.
