ilar, both features are explained in this manual.

• Introduction

features, what each feature consists of, and the function of each feature.
• Theory of Operation
explains the microprograms and data flow of each feature, the
data format used with both features, the EIA (Electronics Industry Association)
RS232C/CCITT V.24-V.28 standard interface lines that both features use, and how
the expansion feature card functions in both transmit and receive operations.
• Diagnostic Aids
tells what diagnostic aids are available for communications and serial
I/O. This section also contains instructions on how to use the diagnostic buffer and
network analysis routine for communications, and contains a troubleshooting guide
for communications and serial I/O.
• Communications Networks
