CDSIO is a 6U VME bus board w/ 6 serial ports. ASO
is an HIO bus card that has sound as well as 6 serial ports.
The ASO uses 68332 to buffer up the data. I belive you can
get some long latency (~20 chars or so if I remeber)
because of the way the ASO firmware buffers up the data.
The CDSIO goes back aways, I had one but I don't
remeber any serious problems. I do not know what the
plans are to supoort it in 6.4.

I think there are 3rd party cards, don't know about drivers.

Yes you can write a user level scsi driver, see the
device driver programming guide in insight (it is not
installed by default)

Don't know.

No.

Most people use the serial ports. Take a look at
man termio. Open the device, set it up with ioctl
struct termios tty_ctrl;
status = ioctl( tty_fd, TCSETAF, &tty_ctrl); /* assign termios values */
if( status == ERROR )
{
(void)fprintf(stderr, "Error set termios struct: %s\n",
strerror(errno));
exit(ERROR);
}
then use read an write. you probably want to
sproc a process to do this.
Have fun
