Chapter 8 Serial An D Parallel Input/Output Introduction - Zenith Z-100 Reference Manual

Chapter 8
Serial and Parallel Input/Output
Introduction
As with most of the other programmable features of the Z-100 PC Series Com-
puters, the easiest and most direct means of manipulating the flow of serial and
parallel data to a real world device (usually a printer), is by means of the routines
provided in the monitor ROM, built into the machine.
However, certain applications may be more efficiently handled by using the infor-
mation provided here, in conjunction with assembly level programming instruc-
tions.
Contained in this chapter is information for the serial and parallel device interrupts,
optional configuration data, and tables showing locations of formatling parameters
and layout architecture for device mapping.
