2ce6dab2 | 63 | * This implements a complex ECMA-48/ISO 6429/ANSI X3.64 type console, |
34a42e78 KL |
64 | * including a scrollback buffer. |
65 | * | |
66 | * <p> | |
67 | * It currently implements VT100, VT102, VT220, and XTERM with the following | |
68 | * caveats: | |
69 | * | |
70 | * <p> | |
bd8d51fa KL |
71 | * - The vttest scenario for VT220 8-bit controls (11.1.2.3) reports a |
72 | * failure with XTERM. This is due to vttest failing to decode the UTF-8 | |
73 | * stream. | |
74 | * | |
75 | * <p> | |
34a42e78 KL |
76 | * - Smooth scrolling, printing, keyboard locking, keyboard leds, and tests |
77 | * from VT100 are not supported. | |
78 | * | |
79 | * <p> | |
80 | * - User-defined keys (DECUDK), downloadable fonts (DECDLD), and VT100/ANSI | |
81 | * compatibility mode (DECSCL) from VT220 are not supported. (Also, | |
82 | * because DECSCL is not supported, it will fail the last part of the | |
83 | * vttest "Test of VT52 mode" if DeviceType is set to VT220.) | |
84 | * | |
85 | * <p> | |
86 | * - Numeric/application keys from the number pad are not supported because | |
87 | * they are not exposed from the TKeypress API. | |
88 | * | |
89 | * <p> | |
90 | * - VT52 HOLD SCREEN mode is not supported. | |
91 | * | |
92 | * <p> | |
93 | * - In VT52 graphics mode, the 3/, 5/, and 7/ characters (fraction | |
94 | * numerators) are not rendered correctly. | |
95 | * | |
96 | * <p> | |
97 | * - All data meant for the 'printer' (CSI Pc ? i) is discarded. | |
