Terminal Support 

Only Hewlett-Packard terminals with memory lock support the command
windows used by the debugger.  Non--Hewlett-Packard terminals or
Hewlett-Packard terminals without memory lock operate in line mode only.
Use the -L command line option when invoking the debugger to operate in
line mode.
