.TH TERM 7 .SH NAME term \- conventional names .SH DESCRIPTION These names are used by certain commands (e.g., .IR nroff (1), .IR mm (1), .IR man (1), .IR tabs (1)) and are maintained as part of the shell environment (see .IR sh (1), .IR profile (5), and .IR environ (7)) in the variable .SM .BR $TERM\*S : .PP .nf .ta \w'300s\-12 'u 1520 Datamedia 1520 1620 Diablo 1620 and others using the HyType II printer 1620\-12 same, in 12-pitch mode 2621 Hewlett-Packard \s-1HP\s+12621 series 2631 Hewlett-Packard 2631 line printer 2631\-c Hewlett-Packard 2631 line printer - compressed mode 2631\-e Hewlett-Packard 2631 line printer - expanded mode 2640 Hewlett-Packard \s-1HP\s+12640 series 2645 Hewlett-Packard \s-1HP\s+1264n series (other than the 2640 series) 300 \s-1DASI/DTC/GSI\s+1 300 and others using the HyType I printer 300\-12 same, in 12-pitch mode 300s \s-1DASI/DTC/GSI\s+1 300s 382 \s-1DTC\s+1 382 300s\-12 same, in 12-pitch mode 3045 Datamedia 3045 33 \s-1TELETYPE\s+1\*R Model 33 \s-1KSR\s+1 37 \s-1TELETYPE\s+1 Model 37 \s-1KSR\s+1 40\-2 \s-1TELETYPE\s+1 Model 40/2 4000A Trendata 4000A 4014 Tektronix 4014 43 \s-1TELETYPE\s+1 Model 43 \s-1KSR\s+1 450 \s-1DASI\s+1 450 (same as Diablo 1620) 450\-12 same, in 12-pitch mode 735 Texas Instruments \s-1TI\s+1735 and \s-1TI\s+1725 745 Texas Instruments \s-1TI\s+1745 dumb generic name for terminals that lack reverse line-feed and other special escape sequences hp Hewlett-Packard (same as 2645) lp generic name for a line printer tn1200 General Electric TermiNet 1200 tn300 General Electric TermiNet 300 .fi .PP Up to 8 characters, chosen from [\-a\-z0\-9], make up a basic terminal name. Terminal sub-models and operational modes are distinguished by suffixes beginning with a \f3\-\fP. Names should generally be based on original vendors, rather than local distributors. A terminal acquired from one vendor should not have more than one distinct basic name. .PP Commands whose behavior depends on the type of terminal should accept arguments of the form .BI \-T term\^ where .I term\^ is one of the names given above; if no such argument is present, such commands should obtain the terminal type from the environment variable .SM .BR $TERM\*S , which, in turn, should contain .IR term . .SH SEE ALSO mm(1), nroff(1), tplot(1G), sh(1), stty(1), tabs(1), profile(5), environ(7). .SH BUGS This is a small candle trying to illuminate a large, dark problem. Programs that ought to adhere to this nomenclature do so somewhat fitfully.
