Keyboard Codes And Legends - Control Data Corporation INFORMATION SYSTEMS TERMINAL II Hardware Maintenance Manual

KEYBOARD
The terminal keyboard provides for operator entry of spe-
cific symbol and control codes. The codes generated by the
keyboard are illustrated in figure 4-23. The function of
the keys is not defined because every key pressed at the
terminal becomes a 7-bit code, processed by the
app~ication
program being executedJ therefore, this code can take t'he
form of displayable data, control commands, and/or informa-
tion to be passed on to the central computer.
