Terminal Keyboard Layouts 

Hewlett-Packard terminals contain keys for the entire ASCII character
set.  These characters can be displayed on the CRT screen and printed on
a printer.  HP terminals have three modes of operation:

   *   Local (not connected to the HP 3000 system)
   *   Remote character mode
   *   Remote block mode

Non-printable keys include the SHIFT, BACKSPACE, RETURN, and TAB keys.
The ESC (escape) and CTRL (control) keys generate special codes for
terminal operation.  The most frequently used codes are the following key
combinations (not case sensitive):

 CTRL-Y                                 stop subsystem activity

 CTRL-S                                 suspend output

 CTRL-Q                                 resume output

Terminals come with various memory amounts.  This affects the amount of
information you can access at one time.  When each line of the screen is
filled, the top line scrolls up to make room for a new line at the
bottom.  This continues until terminal memory is filled.  At this point,
information will be lost from view when you enter another line because
the line scrolled up at the top of the memory buffer is no longer
available.
