Block Mode Operation
6530 Programmer’s Guide 3-7
Table 3-2 lists the control codes and escape sequences that are recognized
in block mode. The ASCII codes for the control characters (other than the
Esc character, which is 1BH) are shown in parentheses. The control codes
and escape sequences are organized into logical groups according to
function. In many cases, the functions they perform are somewhat
different in nonprotect and protect submodes. The following paragraphs
discuss each group and control code or escape sequence in detail.
With the exception of SO and SI control characters, the user cannot
generate control codes or escape sequences from the keyboard in block
mode.
