| 5 | ** TSET -- set terminal modes |
| 6 | ** |
| 7 | ** This program does sophisticated terminal initialization. |
| 8 | ** I recommend that you include it in your .start_up or .login |
| 9 | ** file to initialize whatever terminal you are on. |
| 10 | ** |
| 11 | ** There are several features: |
| 12 | ** |
| 13 | ** A special file or sequence (as controlled by the ttycap file) |
| 14 | ** is sent to the terminal. |
| 15 | ** |
| 16 | ** Mode bits are set on a per-terminal_type basis (much better |
| 17 | ** than UNIX itself). This allows special delays, automatic |
| 18 | ** tabs, etc. |
| 19 | ** |
| 20 | ** Erase and Kill characters can be set to whatever you want. |
| 21 | ** Default is to change erase to control-H on a terminal which |
| 22 | ** can overstrike, and leave it alone on anything else. Kill |
| 23 | ** is always left alone unless specifically requested. These |
| 24 | ** characters can be represented as "^X" meaning control-X; |
| 25 | ** X is any character. |
| 26 | ** |
| 27 | ** Terminals which are dialups or plugboard types can be aliased |
| 28 | ** to whatever type you may have in your home or office. Thus, |
| 29 | ** if you know that when you dial up you will always be on a |
| 30 | ** TI 733, you can specify that fact to tset. You can represent |
| 31 | ** a type as "?type". This will ask you what type you want it |
| 32 | ** to be -- if you reply with just a newline, it will default |
| 33 | ** to the type given. |
| 34 | ** |
| 35 | ** The htmp file, used by ex, etc., can be updated. |
| 36 | ** |
| 37 | ** The current terminal type can be queried. |
| 38 | ** |
| 39 | ** Usage: |
| 40 | ** tset [-] [-EC] [-eC] [-kC] [-s] [-h] [-u] [-r] |
| 41 | ** [-m [ident] [test baudrate] :type] |
| 42 | ** [-Q] [-I] [-S] [type] |
| 43 | ** |
| 44 | ** In systems with environments, use: |
| 45 | ** eval `tset -s ...` |
| 46 | ** Actually, this doesn't work in old csh's. |
| 47 | ** Instead, use: |
| 48 | ** tset -s ... > tset.tmp |
| 49 | ** source tset.tmp |
| 50 | ** rm tset.tmp |
| 51 | ** or: |
| 52 | ** set noglob |
| 53 | ** set term=(`tset -S ....`) |
| 54 | ** setenv TERM $term[1] |
| 55 | ** setenv TERMCAP "$term[2]" |
| 56 | ** unset term |
| 57 | ** unset noglob |
| 58 | ** |
| 59 | ** Positional Parameters: |
| 60 | ** type -- the terminal type to force. If this is |
| 61 | ** specified, initialization is for this |
| 62 | ** terminal type. |
| 63 | ** |
| 64 | ** Flags: |
| 65 | ** - -- report terminal type. Whatever type is |
| 66 | ** decided on is reported. If no other flags |
| 67 | ** are stated, the only affect is to write |
| 68 | ** the terminal type on the standard output. |
| 69 | ** -r -- report to user in addition to other flags. |
| 70 | ** -EC -- set the erase character to C on all terminals |
| 71 | ** except those which cannot backspace (e.g., |
| 72 | ** a TTY 33). C defaults to control-H. |
| 73 | ** -eC -- set the erase character to C on all terminals. |
| 74 | ** C defaults to control-H. If neither -E or -e |
| 75 | ** are specified, the erase character is set to |
| 76 | ** control-H if the terminal can both backspace |
| 77 | ** and not overstrike (e.g., a CRT). If the erase |
| 78 | ** character is NULL (zero byte), it will be reset |
| 79 | ** to '#' if nothing else is specified. |
| 80 | ** -kC -- set the kill character to C on all terminals. |
| 81 | ** Default for C is control-X. If not specified, |
| 82 | ** the kill character is untouched; however, if |
| 83 | ** not specified and the kill character is NULL |
| 84 | ** (zero byte), the kill character is set to '@'. |
| 85 | ** -iC -- reserved for setable interrupt character. |
| 86 | ** -qC -- reserved for setable quit character. |
| 87 | ** -m -- map the system identified type to some user |
| 88 | ** specified type. The mapping can be baud rate |
| 89 | ** dependent. This replaces the old -d, -p flags. |
| 90 | ** (-d type -> -m dialup:type) |
| 91 | ** (-p type -> -m plug:type) |
| 92 | ** Syntax: -m identifier [test baudrate] :type |
| 93 | ** where: ``identifier'' is whatever is found in |
| 94 | ** /etc/ttytype for this port, (abscence of an identifier |
| 95 | ** matches any identifier); ``test'' may be any combination |
| 96 | ** of > = < ! @; ``baudrate'' is as with stty(1); |
| 97 | ** ``type'' is the actual terminal type to use if the |
| 98 | ** mapping condition is met. Multiple maps are scanned |
| 99 | ** in order and the first match prevails. |
| 100 | ** -n -- If the new tty driver from UCB is available, this flag |
| 101 | ** will activate the new options for erase and kill |
| 102 | ** processing. This will be different for printers |
| 103 | ** and crt's. For crts, if the baud rate is < 1200 then |
| 104 | ** erase and kill don't remove characters from the screen. |
| 105 | ** -h -- don't read htmp file. Normally the terminal type |
| 106 | ** is determined by reading the htmp file or the |
| 107 | ** environment (unless some mapping is specified). |
| 108 | ** This forces a read of the ttytype file -- useful |
| 109 | ** when htmp is somehow wrong. (V6 only) |
| 110 | ** -u -- don't update htmp. It seemed like this should |
| 111 | ** be put in. Note that htmp is never actually |
| 112 | ** written if there are no changes, so don't bother |
| 113 | ** bother using this for efficiency reasons alone. |
| 114 | ** -s -- output setenv commands for TERM. This can be |
| 115 | ** used with |
| 116 | ** `tset -s ...` |
| 117 | ** and is to be prefered to: |
| 118 | ** setenv TERM `tset - ...` |
| 119 | ** because -s sets the TERMCAP variable also. |
| 120 | ** -S -- Similar to -s but outputs 2 strings suitable for |
| 121 | ** use in csh .login files as follows: |
| 122 | ** set noglob |
| 123 | ** set term=(`tset -S .....`) |
| 124 | ** setenv TERM $term[1] |
| 125 | ** setenv TERMCAP "$term[2]" |
| 126 | ** unset term |
| 127 | ** unset noglob |
| 128 | ** -Q -- be quiet. don't output 'Erase set to' etc. |
| 129 | ** -I -- don't do terminal initialization (is & if |
| 130 | ** strings). |
| 131 | ** -v -- On virtual terminal systems, don't set up a |
| 132 | ** virtual terminal. Otherwise tset will tell |
| 133 | ** the operating system what kind of terminal you |
| 134 | ** are on (if it is a known terminal) and fix up |
| 135 | ** the output of -s to use virtual terminal sequences. |
| 136 | ** |
| 137 | ** Files: |
| 138 | ** /etc/ttytype |
| 139 | ** contains a terminal id -> terminal type |
| 140 | ** mapping; used when any user mapping is specified, |
| 141 | ** or the environment doesn't have TERM set. |
| 142 | ** /etc/termcap |
| 143 | ** a terminal_type -> terminal_capabilities |
| 144 | ** mapping. |
| 145 | ** |
| 146 | ** Return Codes: |
| 147 | ** -1 -- couldn't open ttycap. |
| 148 | ** 1 -- bad terminal type, or standard output not tty. |
| 149 | ** 0 -- ok. |
| 150 | ** |
| 151 | ** Defined Constants: |
| 152 | ** DIALUP -- the type code for a dialup port. |
| 153 | ** PLUGBOARD -- the type code for a plugboard port. |
| 154 | ** ARPANET -- the type code for an arpanet port. |
| 155 | ** BACKSPACE -- control-H, the default for -e. |
| 156 | ** CTRL('X') -- control-X, the default for -k. |
| 157 | ** OLDERASE -- the system default erase character. |
| 158 | ** OLDKILL -- the system default kill character. |
| 159 | ** FILEDES -- the file descriptor to do the operation |
| 160 | ** on, nominally 1 or 2. |
| 161 | ** STDOUT -- the standard output file descriptor. |
| 162 | ** UIDMASK -- the bit pattern to mask with the getuid() |
| 163 | ** call to get just the user id. |
| 164 | ** GTTYN -- defines file containing generalized ttynames |
| 165 | ** and compiles code to look there. |
| 166 | ** |
| 167 | ** Requires: |
| 168 | ** Routines to handle htmp, ttytype, and ttycap. |
| 169 | ** |
| 170 | ** Compilation Flags: |
| 171 | ** OLDFLAGS -- must be defined to compile code for any of |
| 172 | ** the -d, -p, or -a flags. |
| 173 | ** OLDDIALUP -- accept the -d flag. |
| 174 | ** OLDPLUGBOARD -- accept the -p flag. |
| 175 | ** OLDARPANET -- accept the -a flag. |
| 176 | ** FULLLOGIN -- if defined, login sets the ttytype from |
| 177 | ** /etc/ttytype file. |
| 178 | ** V6 -- if clear, use environments, not htmp. |
| 179 | ** also use TIOCSETN rather than stty to avoid flushing |
| 180 | ** GTTYN -- if set, compiles code to look at /etc/ttytype. |
| 181 | ** UCB_NTTY -- set to handle new tty driver modes. |
| 182 | ** |
| 183 | ** Trace Flags: |
| 184 | ** none |
| 185 | ** |
| 186 | ** Diagnostics: |
| 187 | ** Bad flag |
| 188 | ** An incorrect option was specified. |
| 189 | ** Too few args |
| 190 | ** more command line arguments are required. |
| 191 | ** Unexpected arg |
| 192 | ** wrong type of argument was encountered. |
| 193 | ** Cannot open ... |
| 194 | ** The specified file could not be openned. |
| 195 | ** Type ... unknown |
| 196 | ** An unknown terminal type was specified. |
| 197 | ** Cannot update htmp |
| 198 | ** Cannot update htmp file when the standard |
| 199 | ** output is not a terminal. |
| 200 | ** Erase set to ... |
| 201 | ** Telling that the erase character has been |
| 202 | ** set to the specified character. |
| 203 | ** Kill set to ... |
| 204 | ** Ditto for kill |
| 205 | ** Erase is ... Kill is ... |
| 206 | ** Tells that the erase/kill characters were |
| 207 | ** wierd before, but they are being left as-is. |
| 208 | ** Not a terminal |
| 209 | ** Set if FILEDES is not a terminal. |
| 210 | ** |
| 211 | ** Compilation Instructions: |
| 212 | ** cc -n -O tset.c -ltermlib |
| 213 | ** mv a.out tset |
| 214 | ** chown bin tset |
| 215 | ** chmod 4755 tset |
| 216 | ** |
| 217 | ** where 'bin' should be whoever owns the 'htmp' file. |
| 218 | ** If 'htmp' is 666, then tset need not be setuid. |
| 219 | ** |
| 220 | ** For version 6 the compile command should be: |
| 221 | ** cc -n -O -I/usr/include/retrofit tset.c -ltermlib -lretro -lS |

| 227 | ** |
| 228 | ** History: |
| 229 | ** 1/81 -- Added alias checking for mapping identifiers. |
| 230 | ** 9/80 -- Added UCB_NTTY mods to setup the new tty driver. |
| 231 | ** Added the 'reset ...' invocation. |
| 232 | ** 7/80 -- '-S' added. '-m' mapping added. TERMCAP string |
| 233 | ** cleaned up. |
| 234 | ** 3/80 -- Changed to use tputs. Prc & flush added. |
| 235 | ** 10/79 -- '-s' option extended to handle TERMCAP |
| 236 | ** variable, set noglob, quote the entry, |
| 237 | ** and know about the Bourne shell. Terminal |
| 238 | ** initialization moved to before any information |
| 239 | ** output so screen clears would not screw you. |
| 240 | ** '-Q' option added. |
| 241 | ** 8/79 -- '-' option alone changed to only output |
| 242 | ** type. '-s' option added. 'VERSION7' |
| 243 | ** changed to 'V6' for compatibility. |
| 244 | ** 12/78 -- modified for eventual migration to VAX/UNIX, |
| 245 | ** so the '-' option is changed to output only |
| 246 | ** the terminal type to STDOUT instead of |
| 247 | ** FILEDES. FULLLOGIN flag added. |
| 248 | ** 9/78 -- '-' and '-p' options added (now fully |
| 249 | ** compatible with ttytype!), and spaces are |
| 250 | ** permitted between the -d and the type. |
| 251 | ** 8/78 -- The sense of -h and -u were reversed, and the |
| 252 | ** -f flag is dropped -- same effect is available |
| 253 | ** by just stating the terminal type. |
| 254 | ** 10/77 -- Written. |
