    In reading an older epat.c, you'll notice something like

    static void epat_connect ( PIA *pi )

    { pi->saved_r0 = r0();
            pi->saved_r2 = r2();
            CCP(0); CCP(0xe0);
            w0(0); w2(1); w2(4);
            if (pi->mode >= 3) {

    the 'w0();w2(1);w2(4);' is executing a software reset on the EPAT chip.

    Perhaps the source should mention that...
