Hi,

I've just changed the ppa.c code back to:

        if (ppa_in(host_no, &l, 1)) { /* read status byte */
            /* Check for optional message byte */
            if (ppa_wait(host_no) == (unsigned char) 0xf0)
                printk("ppa.c: line 907\n");
                ppa_in(host_no, &h, 1);
                printk("ppa.c: line 910\n");

            cmd->result = (DID_OK << 16) + (h << 8) + (l & STATUS_MASK);

/* cmd->result = (DID_OK << 16) + (l & STATUS_MASK); */

And commented out the following code further up:

        /* Mode detection works up the chain of speed
         * This avoids a nasty if-then-else-if-... tree
         */
        ppa_hosts[i].mode = PPA_NIBBLE;

/* if (modes & PARPORT_MODE_PCPS2)
            ppa_hosts[i].mode = PPA_PS2;

        if (modes & PARPORT_MODE_PCECPPS2) {
            w_ecr(ppb, 0x20);
            ppa_hosts[i].mode = PPA_PS2;
        }
        if (modes & PARPORT_MODE_PCECPEPP)
            w_ecr(ppb, 0x80);
*/

I now run in SPP mode with the result:

ppa: Version 2.03 (for Linux 2.2.x)

And it works. I can run with this for the time being, but presumably I can
get more from the port?
