NAMEhp — handle special functions of HP2640 and HP2621-series terminals DESCRIPTIONhp supports special functions of the Hewlett-Packard HP 2640 and HP 2621 series of terminals, with the primary purpose of producing accurate representations of most nroff output. A typical use is: nroff -h files ... | hp Regardless of the hardware options on a given terminal, hp tries to do sensible things with underlining and reverse line-feeds. If the terminal has the ``display enhancements'' feature, subscripts and superscripts can be indicated in distinct ways. If it has the ``mathematical-symbol'' feature, Greek and other special characters can be displayed. Optionshp recognizes the following options:
WARNINGSAn ``overstriking sequence'' is defined as a printing character followed by a backspace followed by another printing character. In such sequences, if either printing character is an underscore, the other printing character is shown underlined or in Inverse Video; otherwise, only the first printing character is shown (again, underlined or in Inverse Video). Nothing special is done if a backspace is adjacent to an ASCII control character. Sequences of control characters (e.g., reverse line-feeds, backspaces) can make text ``disappear''; in particular, tables generated by tbl that contain vertical lines will often be missing the lines of text that contain the ``foot'' of a vertical line, unless the input to hp is piped through col (see col(1)). Although some terminals do support numerical superscript characters, no attempt is made to display them. |
