There is an excellent series of application notes regarding Z80 interrupts
and asynchronous communications in Zilog's "Microprocessor Applications
Reference Book, Volume 1." There are two in-depth articles on asynchronous
applications of the DART/SIO, as well as a good article on synchronous SIO
programming. In addition, there are several other articles that deal with
interrupt-driven use of the CTC, etc. Each article includes commented
assembly language code.

You should be able to obtain a copy of this book from Zilog Sales and
Technical Center, 10340 Bubb Road, Cupertino, CA 95014. Their phone number
is (408) 446-9848. These books were often given free of charge to designers
using the Z80, so perhaps Zilog will sell one for a nominal cost.
