The string valued options 88 * are the most complicated, since they may include padding information, 89 * which we describe now. 90 * 91 * Intelligent terminals often require padding on intelligent operations 92 * at high (and sometimes even low) speed. This is specified by 93 * a number before the string in the capability, and has meaning for the 94 * capabilities which have a P at the front of their comment. 95 * This normally is a number of milliseconds to pad the operation. 96 * In the current system which has no true programmible delays, we 97 * do this by sending a sequence of pad characters (normally nulls, but 98 * specifiable as "pc"). In some cases, the pad is better computed 99 * as some number of milliseconds times the number of affected lines 100 * (to bottom of screen usually, except when terminals have insert modes 101 * which will shift several lines.) This is specified as '12*' e.g. 102 * before the capability to say 12 milliseconds per affected whatever 103 * (currently always line). Capabilities where this makes sense say P*. 104 */ 105 #ifndef VMUNIX 106 var char tspace[256]; /* Space for capability strings */ 107 #else 108 var char tspace[1024]; /* Space for capability strings */ 109 #endif 110 var char *aoftspace; /* Address of tspace for relocation */ 111 112 var char *AL; /* P* Add new blank line */ 113 var char *AL_PARM; /* P* Add n new blank lines */ 114 extern char *BC; /* Back cursor */ 115 var char *BT; /* P Back tab */ 116 var char *CD; /* P* Clear to end of display */ 117 var char *CE; /* P Clear to end of line */ 118 var char *CL; /* P* Clear screen */ 119 var char *CM; /* PG Cursor motion */ 120 var char *xCS; /* PG Change scrolling region (vt100) */ 121 var char *xCR; /* P Carriage return */ 122 var char *DC; /* P* Delete character */ 123 var char *DL; /* P* Delete line sequence */ 124 var char *DL_PARM; /* P* Delete n lines */ 125 var char *DM; /* Delete mode (enter) */ 126 var char *DO; /* Down line sequence */ 127 var char *DOWN_PARM; /* Down n lines */ 128 var char *ED; /* End delete mode */ 129 var char *EI; /* End insert mode */ 130 var char *F0,*F1,*F2,*F3,*F4,*F5,*F6,*F7,*F8,*F9; 131 /* Strings sent by various function keys */ 132 var char *HO; /* Home cursor */ 133 var char *IC; /* P Insert character */ 134 var char *IM; /* Insert mode (give as ':im=:' if 'ic' */ 135 var char *IP; /* P* Insert pad after char ins'd using IM+IE */ 136 var char *KD; /* Keypad down arrow */ 137 var char *KE; /* Keypad don't xmit */ 138 var char *KH; /* Keypad home key */ 139 var char *KL; /* Keypad left arrow */ 140 var char *KR; /* Keypad right arrow */ 141 var char *KS; /* Keypad start xmitting */ 142 var char *KU; /* Keypad up arrow */ 143 var char *LEFT_PARM; /* Left n chars */ 144 var char *LL; /* Quick to last line, column 0 */ 145 var char *ND; /* Non-destructive space */ 146 var char *RIGHT_PARM; /* Right n spaces */ 147 var char *xNL; /* Line feed (new line) */ 148 extern char PC; /* Pad character */ 149 var char *RC; /* Restore cursor from last SC */ 150 var char *SC; /* Save cursor */ 151 var char *SE; /* Standout end (may leave space) */ 152 var char *SF; /* P Scroll forwards */ 153 var char *SO; /* Stand out begin (may leave space) */ 154 var char *SR; /* P Scroll backwards */ 155 var char *TA; /* P Tab (other than ^I or with padding) */ 156 var char *TE; /* Terminal end sequence */ 157 var char *TI; /* Terminal initial sequence */ 158 extern char *UP; /* Upline */ 159 var char *UP_PARM; /* Up n lines */ 160 var char *VB; /* Visible bell */ 161 var char *VE; /* Visual end sequence */ 162 var char *VS; /* Visual start sequence */ 163 var bool AM; /* Automatic margins */ 164 var bool BS; /* Backspace works */ 165 var bool CA; /* Cursor addressible */ 166 var bool DA; /* Display may be retained above */ 167 var bool DB; /* Display may be retained below */ 168 var bool EO; /* Can erase overstrikes with ' ' */ 169 var bool GT; /* Gtty indicates tabs */ 170 var bool HC; /* Hard copy terminal */ 171 #ifdef UCVISUAL 172 var bool xHZ; /* Hazeltine ~ braindamage */ 173 #endif 174 var bool IN; /* Insert-null blessing */ 175 var bool MI; /* can move in insert mode */ 176 var bool NC; /* No Cr - \r snds \r\n then eats \n (dm2500) */ 177 var bool NS; /* No scroll - linefeed at bottom won't scroll */ 178 var bool OS; /* Overstrike works */ 179 var bool UL; /* Underlining works even though !os */ 180 var bool XB; /* Beehive (no escape key, simulate with f1) */ 181 var bool XN; /* A newline gets eaten after wrap (concept) */ 182 var bool XT; /* Tabs are destructive */ 183 var bool XX; /* Tektronix 4025 insert line */ 184 /* X?
