67 | * including a scrollback buffer. |
68 | * | |
69 | * <p> | |
70 | * It currently implements VT100, VT102, VT220, and XTERM with the following | |
71 | * caveats: | |
72 | * | |
73 | * <p> | |
bd8d51fa KL |
74 | * - The vttest scenario for VT220 8-bit controls (11.1.2.3) reports a |
75 | * failure with XTERM. This is due to vttest failing to decode the UTF-8 | |
76 | * stream. | |
77 | * | |
78 | * <p> | |
34a42e78 KL |
79 | * - Smooth scrolling, printing, keyboard locking, keyboard leds, and tests |
80 | * from VT100 are not supported. | |
81 | * | |
82 | * <p> | |
83 | * - User-defined keys (DECUDK), downloadable fonts (DECDLD), and VT100/ANSI | |
84 | * compatibility mode (DECSCL) from VT220 are not supported. (Also, | |
85 | * because DECSCL is not supported, it will fail the last part of the | |
86 | * vttest "Test of VT52 mode" if DeviceType is set to VT220.) | |
87 | * | |
88 | * <p> | |
89 | * - Numeric/application keys from the number pad are not supported because | |
90 | * they are not exposed from the TKeypress API. | |
91 | * | |
92 | * <p> | |
93 | * - VT52 HOLD SCREEN mode is not supported. | |
94 | * | |
95 | * <p> | |
96 | * - In VT52 graphics mode, the 3/, 5/, and 7/ characters (fraction | |
97 | * numerators) are not rendered correctly. | |
98 | * | |
99 | * <p> | |
100 | * - All data meant for the 'printer' (CSI Pc ? i) is discarded. | |
