4818099Spstinto a form suitable for typewriter-like devices. 4918099SpstNormally 5018099Spst.B grotty 5175590Srushould be invoked by using the 5218099Spst.B groff 5318099Spstcommand 5418099Spstwith a

63104868Sru.B \-Tutf8 6469631Sruon EBCDIC based hosts. 6518099SpstIf no files are given, 6618099Spst.B grotty 6718099Spstwill read the standard input. 6818099SpstA filename of 6918099Spst.B \- 7018099Spstwill also cause 7118099Spst.B grotty 7218099Spstto read the standard input. 7318099SpstOutput is written to the standard output. 7418099Spst.LP 75104868SruBy default, 7618099Spst.B grotty 77104868Sruemits SGR escape sequences (from ISO 6429, also called ANSI color escapes) 78104868Sruto change text attributes (bold, italic, colors). 79104868SruThis makes it possible to have eight different \M[green]background\M[] 80104868Sruand \m[red]foreground\m[] colors; additionally, bold and italic 81104868Sruattributes can be used \f[BI]at the same time\f[] (by using the BI font). 82104868Sru.LP 83104868SruThe following colors are defined in 84104868Sru.BR tty.tmac : 85104868Srublack, white, red, green, blue, yellow, magenta, cyan. 86104868SruUnknown colors are mapped to the default color (which is dependent on the 87104868Srusettings of the terminal; in most cases, this is black for the foreground 88104868Sruand white for the background). 89104868Sru.LP 90104868SruUse the 91104868Sru.B \-c 92104868Sruswitch to revert to the old behaviour, printing a bold character 9318099Spst.I c 94104868Sruwith the sequence 9518099Spst.RI ` c 9618099Spst.SM BACKSPACE 9718099Spst.IR c ' 98104868Sruand an italic character 9918099Spst.I c 10018099Spstby the sequence 10118099Spst.RB ` _ 10218099Spst.SM BACKSPACE 10318099Spst.IR c '. 104104868SruAt the same time, color output is disabled. 105104868SruThe same effect can be achieved by setting either the 106104868Sru.B GROFF_NO_SGR 107104868Sruenvironment variable or using the `sgr' X command (see below). 108104868Sru.LP 109104868SruFor SGR support, it is necessary to use the 110104868Sru.B \-R 111104868Sruoption of 112104868Sru.BR less (1) 113104868Sruto disable the interpretation of 114104868Sru.BR
