I have recently built a Big Board and I am attempting to use it
as a teminal (initially) to our UNIX system.

I have had some difficulty understanding Zilog's documentation on
the Z80 SIO as evidenced by the fact I cannot get either SIO A or B
to give me anything on a write other than transmit data overrun??

If anyone has any experience with this particular system I sure
would like to here from you.

				thanks
