Entering Debugger Command Lines
187Bug is command-driven and performs its various operations in
response to user commands entered at the keyboard. When the
debugger prompt
187-Bug>
appears on the terminal screen, then the debugger is ready to accept
commands.
Terminal Input/Output Control
As the command line is entered, it is stored in an internal buffer.
Execution begins only after the carriage return is entered, so that
you can correct entry errors, if necessary, using the control
characters described below.
