Computer Interface and Commands 8-3
Computer Commands
The commands that are transmitted to the CPC are ASCII strings;
they are followed by a carriage return and a line feed. In response
to any incorrect or undecipherable transmissions, the CPC
transmits the word ERROR
followed by a carriage return and line
feed. Table 8-2 lists the commands and the CPC responses. A
simple computer program written in
BASIC is listed in the next
section to demonstrate the possible interfacing that you can do with
the CPC.

“x” is any voltage in units of one-
tenth of a volt. For example, 1 = 0.1
volt and 120 = 12.0 volts. “y” is
