The four ring plug was originally specified as we needed four signals (Tx,Rx,DTR and Gnd). The final product doesn't need DTR, and the standard stereo mini-jack will work just fine.
The link runs at 115 Kbaud, and handshaking isn't usually necessary, since both ends run fast enough to keep up. But it does use software handshaking.
