19 | ** TSET -- set terminal modes | |
20 | ** | |
21 | ** This program does sophisticated terminal initialization. | |
0b1d4860 | 22 | ** I recommend that you include it in your .profile or .login |
177ed6dd BJ |
23 | ** file to initialize whatever terminal you are on. |
24 | ** | |
25 | ** There are several features: | |
26 | ** | |
0b1d4860 | 27 | ** A special file or sequence (as controlled by the termcap file) |
177ed6dd BJ |
28 | ** is sent to the terminal. |
29 | ** | |
30 | ** Mode bits are set on a per-terminal_type basis (much better | |
31 | ** than UNIX itself). This allows special delays, automatic | |
32 | ** tabs, etc. | |
33 | ** | |
34 | ** Erase and Kill characters can be set to whatever you want. | |
35 | ** Default is to change erase to control-H on a terminal which | |
36 | ** can overstrike, and leave it alone on anything else. Kill | |
37 | ** is always left alone unless specifically requested. These | |
38 | ** characters can be represented as "^X" meaning control-X; | |
39 | ** X is any character. | |
40 | ** | |
41 | ** Terminals which are dialups or plugboard types can be aliased | |
42 | ** to whatever type you may have in your home or office. Thus, | |
43 | ** if you know that when you dial up you will always be on a | |
44 | ** TI 733, you can specify that fact to tset. You can represent | |
45 | ** a type as "?type". This will ask you what type you want it | |
46 | ** to be -- if you reply with just a newline, it will default | |
47 | ** to the type given. | |
48 | ** | |
177ed6dd BJ |
49 | ** The current terminal type can be queried. |
50 | ** | |
51 | ** Usage: | |
0b1d4860 | 52 | ** tset [-] [-EC] [-eC] [-kC] [-iC] [-s] [-h] [-u] [-r] |
177ed6dd BJ |
53 | ** [-m [ident] [test baudrate] :type] |
54 | ** [-Q] [-I] [-S] [type] | |
55 | ** | |
56 | ** In systems with environments, use: | |
6a19f69a BJ |
57 | ** eval `tset -s ...` |
58 | ** Actually, this doesn't work in old csh's. | |
177ed6dd BJ |
59 | ** Instead, use: |
60 | ** tset -s ... > tset.tmp | |
61 | ** source tset.tmp | |
62 | ** rm tset.tmp | |
63 | ** or: | |
64 | ** set noglob | |
65 | ** set term=(`tset -S ....`) | |
66 | ** setenv TERM $term[1] | |
67 | ** setenv TERMCAP "$term[2]" | |
68 | ** unset term | |
69 | ** unset noglob | |
70 | ** | |
71 | ** Positional Parameters: | |
72 | ** type -- the terminal type to force. If this is | |
73 | ** specified, initialization is for this | |
74 | ** terminal type. | |
75 | ** | |
76 | ** Flags: | |
77 | ** - -- report terminal type. Whatever type is | |
78 | ** decided on is reported. If no other flags | |
79 | ** are stated, the only affect is to write | |
80 | ** the terminal type on the standard output. | |
81 | ** -r -- report to user in addition to other flags. | |
82 | ** -EC -- set the erase character to C on all terminals | |
83 | ** except those which cannot backspace (e.g., | |
84 | ** a TTY 33). C defaults to control-H. | |
85 | ** -eC -- set the erase character to C on all terminals. | |
0b1d4860 JB |
86 | ** C defaults to control-H. If not specified, |
87 | ** the erase character is untouched; however, if | |
88 | ** not specified and the erase character is NULL | |
89 | ** (zero byte), the erase character is set to delete. | |
177ed6dd BJ |
90 | ** -kC -- set the kill character to C on all terminals. |
91 | ** Default for C is control-X. If not specified, | |
92 | ** the kill character is untouched; however, if | |
93 | ** not specified and the kill character is NULL | |
0b1d4860 | 94 | ** (zero byte), the kill character is set to control-U. |
77f8c4bb | 95 | ** -iC -- set the interrupt character to C on all terminals. |
0b1d4860 JB |
96 | ** Default for C is control-C. If not specified, the |
97 | ** interrupt character is untouched; however, if | |
98 | ** not specified and the interrupt character is NULL | |
99 | ** (zero byte), the interrupt character is set to | |
100 | ** control-C. | |
177ed6dd BJ |
101 | ** -qC -- reserved for setable quit character. |
102 | ** -m -- map the system identified type to some user | |
103 | ** specified type. The mapping can be baud rate | |
104 | ** dependent. This replaces the old -d, -p flags. | |
105 | ** (-d type -> -m dialup:type) | |
106 | ** (-p type -> -m plug:type) | |
107 | ** Syntax: -m identifier [test baudrate] :type | |
9479aa87 BJ |
108 | ** where: ``identifier'' is terminal type found in |
109 | ** /etc/ttys for this port, (abscence of an identifier | |
177ed6dd BJ |
110 | ** matches any identifier); ``test'' may be any combination |
111 | ** of > = < ! @; ``baudrate'' is as with stty(1); | |
112 | ** ``type'' is the actual terminal type to use if the | |
113 | ** mapping condition is met. Multiple maps are scanned | |
114 | ** in order and the first match prevails. | |
6a19f69a BJ |
115 | ** -n -- If the new tty driver from UCB is available, this flag |
116 | ** will activate the new options for erase and kill | |
117 | ** processing. This will be different for printers | |
118 | ** and crt's. For crts, if the baud rate is < 1200 then | |
119 | ** erase and kill don't remove characters from the screen. | |
177ed6dd BJ |
120 | ** -h -- don't read htmp file. Normally the terminal type |
121 | ** is determined by reading the htmp file or the | |
122 | ** environment (unless some mapping is specified). | |
123 | ** This forces a read of the ttytype file -- useful | |
6a19f69a | 124 | ** when htmp is somehow wrong. (V6 only) |
177ed6dd BJ |
125 | ** -u -- don't update htmp. It seemed like this should |
126 | ** be put in. Note that htmp is never actually | |
127 | ** written if there are no changes, so don't bother | |
128 | ** bother using this for efficiency reasons alone. | |
129 | ** -s -- output setenv commands for TERM. This can be | |
130 | ** used with | |
131 | ** `tset -s ...` | |
132 | ** and is to be prefered to: | |
133 | ** setenv TERM `tset - ...` | |
134 | ** because -s sets the TERMCAP variable also. | |
135 | ** -S -- Similar to -s but outputs 2 strings suitable for | |
136 | ** use in csh .login files as follows: | |
137 | ** set noglob | |
138 | ** set term=(`tset -S .....`) | |
139 | ** setenv TERM $term[1] | |
140 | ** setenv TERMCAP "$term[2]" | |
141 | ** unset term | |
142 | ** unset noglob | |
143 | ** -Q -- be quiet. don't output 'Erase set to' etc. | |
144 | ** -I -- don't do terminal initialization (is & if | |
145 | ** strings). | |
6a19f69a BJ |
146 | ** -v -- On virtual terminal systems, don't set up a |
147 | ** virtual terminal. Otherwise tset will tell | |
148 | ** the operating system what kind of terminal you | |
149 | ** are on (if it is a known terminal) and fix up | |
150 | ** the output of -s to use virtual terminal sequences. | |
177ed6dd BJ |
151 | ** |
152 | ** Files: | |
9479aa87 | 153 | ** /etc/ttys |
177ed6dd BJ |
154 | ** contains a terminal id -> terminal type |
155 | ** mapping; used when any user mapping is specified, | |
156 | ** or the environment doesn't have TERM set. | |
157 | ** /etc/termcap | |
158 | ** a terminal_type -> terminal_capabilities | |
159 | ** mapping. | |
160 | ** | |
161 | ** Return Codes: | |
162 | ** -1 -- couldn't open ttycap. | |
163 | ** 1 -- bad terminal type, or standard output not tty. | |
164 | ** 0 -- ok. | |
165 | ** | |
166 | ** Defined Constants: | |
6a19f69a BJ |
167 | ** DIALUP -- the type code for a dialup port. |
168 | ** PLUGBOARD -- the type code for a plugboard port. | |
169 | ** ARPANET -- the type code for an arpanet port. | |
177ed6dd | 170 | ** BACKSPACE -- control-H, the default for -e. |
0b1d4860 | 171 | ** CNTL('X') -- control-X, the default for -k. |
177ed6dd BJ |
172 | ** OLDERASE -- the system default erase character. |
173 | ** OLDKILL -- the system default kill character. | |
174 | ** FILEDES -- the file descriptor to do the operation | |
175 | ** on, nominally 1 or 2. | |
176 | ** STDOUT -- the standard output file descriptor. | |
177 | ** UIDMASK -- the bit pattern to mask with the getuid() | |
178 | ** call to get just the user id. | |
179 | ** GTTYN -- defines file containing generalized ttynames | |
180 | ** and compiles code to look there. | |
181 | ** | |
182 | ** Requires: | |
9479aa87 | 183 | ** Routines to handle htmp, ttys, and ttycap. |
177ed6dd BJ |
184 | ** |
185 | ** Compilation Flags: | |
177ed6dd BJ |
186 | ** OLDFLAGS -- must be defined to compile code for any of |
187 | ** the -d, -p, or -a flags. | |
6a19f69a BJ |
188 | ** OLDDIALUP -- accept the -d flag. |
189 | ** OLDPLUGBOARD -- accept the -p flag. | |
190 | ** OLDARPANET -- accept the -a flag. | |
177ed6dd BJ |
191 | ** V6 -- if clear, use environments, not htmp. |
192 | ** also use TIOCSETN rather than stty to avoid flushing | |
9479aa87 | 193 | ** GTTYN -- if set, compiles code to look at /etc/ttys. |
6a19f69a | 194 | ** UCB_NTTY -- set to handle new tty driver modes. |
177ed6dd BJ |
195 | ** |
196 | ** Trace Flags: | |
197 | ** none | |
198 | ** | |
199 | ** Diagnostics: | |
200 | ** Bad flag | |
201 | ** An incorrect option was specified. | |
202 | ** Too few args | |
203 | ** more command line arguments are required. | |
204 | ** Unexpected arg | |
205 | ** wrong type of argument was encountered. | |
206 | ** Cannot open ... | |
207 | ** The specified file could not be openned. | |
208 | ** Type ... unknown | |

215 | ** set to the specified character. | |
216 | ** Kill set to ... | |
217 | ** Ditto for kill | |
218 | ** Erase is ... Kill is ... | |
219 | ** Tells that the erase/kill characters were | |
220 | ** wierd before, but they are being left as-is. | |
221 | ** Not a terminal | |
222 | ** Set if FILEDES is not a terminal. | |
223 | ** | |
224 | ** Compilation Instructions: | |
225 | ** cc -n -O tset.c -ltermlib | |
226 | ** mv a.out tset | |
227 | ** chown bin tset | |
228 | ** chmod 4755 tset | |
229 | ** | |
230 | ** where 'bin' should be whoever owns the 'htmp' file. | |
231 | ** If 'htmp' is 666, then tset need not be setuid. | |
232 | ** | |
6a19f69a BJ |
233 | ** For version 6 the compile command should be: |
234 | ** cc -n -O -I/usr/include/retrofit tset.c -ltermlib -lretro -lS | |

240 | ** | |
241 | ** History: | |
6a19f69a BJ |
242 | ** 1/81 -- Added alias checking for mapping identifiers. |
243 | ** 9/80 -- Added UCB_NTTY mods to setup the new tty driver. | |
244 | ** Added the 'reset ...' invocation. | |
245 | ** 7/80 -- '-S' added. '-m' mapping added. TERMCAP string | |
177ed6dd BJ |
246 | ** cleaned up. |
247 | ** 3/80 -- Changed to use tputs. Prc & flush added. | |
248 | ** 10/79 -- '-s' option extended to handle TERMCAP | |
249 | ** variable, set noglob, quote the entry, | |
250 | ** and know about the Bourne shell. Terminal | |
251 | ** initialization moved to before any information | |
252 | ** output so screen clears would not screw you. | |
253 | ** '-Q' option added. | |
254 | ** 8/79 -- '-' option alone changed to only output | |
255 | ** type. '-s' option added. 'VERSION7' | |
256 | ** changed to 'V6' for compatibility. | |
257 | ** 12/78 -- modified for eventual migration to VAX/UNIX, | |
258 | ** so the '-' option is changed to output only | |
259 | ** the terminal type to STDOUT instead of | |
9479aa87 | 260 | ** FILEDES. |
177ed6dd BJ |
261 | ** 9/78 -- '-' and '-p' options added (now fully |
262 | ** compatible with ttytype!), and spaces are | |
263 | ** permitted between the -d and the type. | |
264 | ** 8/78 -- The sense of -h and -u were reversed, and the | |
265 | ** -f flag is dropped -- same effect is available | |
266 | ** by just stating the terminal type. | |
267 | ** 10/77 -- Written. | |
