The file /_e_t_c/_t_e_r_m_c_a_p is read to determine the appropriate 14 sequences for underlining. If the terminal is incapable of underlining, 15 but is capable of a standout mode then that is used instead. If the 16 terminal can overstrike, or handles underlining automatically, uull 17 degenerates to cat(1). If the terminal cannot underline, underlining is 18 ignored. 19 20 The following options are available: 21 22 --ii Underlining is indicated by a separate line containing 23 appropriate dashes `-'; this is useful when you want to look at 24 the underlining which is present in an nroff output stream on a 25 crt-terminal. 26 27 --tt _t_e_r_m_i_n_a_l 28 Overrides the terminal type specified in the environment with 29 _t_e_r_m_i_n_a_l. 30 31EENNVVIIRROONNMMEENNTT 32 The following environment variable is used: 33 34 TERM The TERM variable is used to relate a tty device with its device 35 capability description (see termcap(5)). TERM is set at login 36 time, either by the default terminal type specified in /_e_t_c/_t_t_y_s or 37 as set during the login process by the user in their _l_o_g_i_n file 38 (see setenv(1)). 39 40SSEEEE AALLSSOO 41 man(1), nroff(1), colcrt(1) 42 43BBUUGGSS 44 Nroff usually outputs a series of backspaces and underlines intermixed 45 with the text to indicate underlining.
