When you get things very cheaply, there's usually a good reason.
Unless you have another one of those same bizarre modems around,
you are probably out of luck.  That unit runs a half-duplex
protocol... it expects a true 4-wire connection for communications
in a "full-duplex" sort of mode.  It is (as far as I know) not
compatible with Vadic 3400, Bell 212A, or any other 1200bps
true FULL-duplex protocols.  Sorry about that.
