1.1 ! root 1: CTerm terminal chariteristics: ! 2: ------------------------------ ! 3: ! 4: End of line behaviour (wrapping): ! 5: The cursor is moved to the first character of the next line ! 6: as soon as a character is written to the last column of the ! 7: current line, not on the next character. A tab will wrap ! 8: to the next line only if the current cursor position is the ! 9: last character on the line. ! 10: ! 11: Control characters: ! 12: ! 13: CR: ! 14: Move cursor position to column 1 of the current line ! 15: ! 16: LF: ! 17: Move cursor position to same column of the next row. ! 18: If current row is the last row, scrolls the screen up ! 19: and fills the new row with the current attribute. ! 20: ! 21: BS: ! 22: Non-destructive backspace. Moves cursor position to ! 23: the previous column unless the current column is the ! 24: first, in which case no operation is performed. ! 25: ! 26: 0x07: ! 27: Beep ! 28: ! 29: TAB: ! 30: Moves to the next tab stop. Does not overwrite any ! 31: characters in between. If the starting position is ! 32: last column, advances to next line. If starting ! 33: position is the last column of the last line, performs ! 34: a scroll, filling the new line at bottom with the ! 35: current attribute and moves to the first character in ! 36: the new line. ! 37: ! 38: Control Codes: ! 39: -------------- ! 40: ! 41: Control codes are in the following format: ! 42: ESC {SPACE to '/'}{'0' (ZERO) to '~'} ! 43: There may be multiple characters from the {SPACE to '/'} set ! 44: before the terminating '0' to '~' ! 45: ! 46: Legal combinations which are not handled are silently dropped. ! 47: ! 48: ESC D (Disabled in current code) ! 49: Scrolls window up one line filling the bottom line with the ! 50: current attribute. ! 51: SOURCE: BANSI.TXT ! 52: ! 53: ESC M (Disabled in current code) ! 54: Scrolls window down one line filling the top line with the ! 55: current attribute ! 56: SOURCE: BANSI.TXT ! 57: ! 58: Control Sequences: ! 59: ------------------ ! 60: ! 61: Control sequences start with the Control Sequence Introducer which is ! 62: ESC [ CSI will be used to express this from now on. ! 63: ! 64: Control sequences are in the following format: ! 65: CSI {'0' (ZERO) to '?'}{SPACE to '/'}{'@' to '~'} ! 66: There may be multiple characters from the {'0' (ZERO) to '?'} ! 67: and {SPACE to '/'} before the terminating {'@' to '~'} character. ! 68: ! 69: Legal combinations not handled are silently dropped. ! 70: Illegal combinations are displayed. ! 71: ! 72: Sequence Parameters: ! 73: Parameters are expressed by the {'0' (ZERO) to '?'} character set. ! 74: Sequences which use parameters use decimal parameters separated by ! 75: a ';'. The use of a ':' from the set is reserved. ! 76: If the parameter string begins with '<', '=', '>', or '?' then ! 77: this is a non-standard extension to the ANSI spec. ! 78: ! 79: Parameters will be shown as pX where X will be a decimal position ! 80: number.

A programmer with either TeleMate or QModem (the first two programs to ! 437: support "ANSI" music as far as I can tell) decided they needed a method of ! 438: playing music on a BBS conenction. They decided to add an "unused" ANSI code ! 439: and go their merry way. Since their product didn't implement CSI M (Delete ! 440: line) they assumed it was unused and blissfully broke the spec. They defined ! 441: "ANSI" music as: ! 442: CSI M <music string> 0x0a ! 443: ! 444: They used a subset of IBM BASICs PLAY statement functionality for ANSI music ! 445: strings which oftem start with "MF" or "MB", so the M after the CSI was often ! 446: considered as part of the music string. You would see things such as: ! 447: CSI MFABCD 0x0a and the F would not be played as a note. This just added ! 448: further confusion to the mess. ! 449: ! 450: Later on, BananaCom realized the conflict between delete line and music, so they ! 451: added *another* broken code CSI N (Properly, erase in field... not implemented ! 452: in many BBS clients) which was to provide an "unbroken" method of playing music ! 453: strings. They also used CSI Y to disambiguate delete line, CSI Y is supposed ! 454: to be a vertical tab (also not implemented in very many clients). BananaCom ! 455: also introduced many more non-standard and stardard-breaking control sequences ! 456: which are not supported by CTerm. ! 457: ! 458: CTerm has further introduced a standard compliant ANSI music introducer CSI | ! 459: ! 460: By default, CTerm allows both CSI N and CSI | to introduce a music string. ! 461: Allowed introducers are set by CSI = p1 M as defined above. ! 462: ! 463: The details of ANSI music are as follows then: ! 464: The following characters are allowed in music strings: ! 465: "aAbBcCdDeEfFgGlLmMnNoOpPsStT0123456789.-+#<> " ! 466: If any character not in this list is present, the music string is ignored as ! 467: is the introducing code. ! 468: ! 469: If the introducing code is CSI M the first char is examined, and if it is ! 470: a one of "BbFfLlSs" or if it is "N" or "n" and is not followed by a decimal ! 471: digit, then the music string is treated as though an M is located in front ! 472: of the first character. ! 473: ! 474: The music string is then parsed with the following sequences supported: ! 475: Mx sets misc music parameters where x is one of the following: ! 476: F - Plays music in the foreground, waiting for music to complete ! 477: playing before more characters are processed. ! 478: B - Play music in the background, allowing normal processing to ! 479: continue. ! 480: N - "Normal" not legato, not stacatto ! 481: L - Play notes legato ! 482: S - Play notes stacatto ! 483: T### Sets the tempo of the music where ### is one or more decimal digits. ! 484: If the decimal number is greater than 255, it is forced to 255. ! 485: If it is less than 32, it is forced to 32. The number signifies ! 486: quarter notes per minute. ! 487: The default tempo is 120. ! 488: O### Sets the octave of the music where ### is one or more decimal digits. ! 489: If the decimal number is greater than 6, it is forced to 6. ! 490: The default octave is 4. ! 491: N### Plays a single note by number. Valid values are 0 - 71. Invalid ! 492: values are played as silence. Note zero is C in octave 0. ! 493: See following section for valid note modifiers. ! 494: A, B, C, D, E, G, or P Plays the named note or pause from the current ! 495: octave. An "Octave" is the rising sequence of the following notes: ! 496: C, C#, D, D#, E, F, F#, G, G#, A, A#, B ! 497: This is contrary to normal music terminology. ! 498: The special note "P" is a pause. ! 499: Notes may be followed by one or more modifier characters which ! 500: are applied in order. If one overrides a previous one, the last ! 501: is used. The valid modifiers are: ! 502: + - Sharp. The next highest semitone is played. ! 503: Each sharp character will move up one semitone, so "C++" ! 504: is equivilent to "D". ! 505: # - Sharp. The next highest semitone is played. ! 506: Each sharp character will move up one semitone, so "C##" ! 507: is equivilent to "D". ! 508: - - Flat. The next lowest semitone is played. ! 509: Each flat character will move down one semitone, so "D--" ! 510: is equivilent to "C". ! 511: . - Duration is 1.5 times what it would otherwise be. Dots are not ! 512: cumulative, so "C.." is equivilent to "C." ! 513: ### - Notelength as a reciprical of the fraction of a whole note to ! 514: play the note for. For example, 4 would indicate a 1/4 note. ! 515: The default note length is 4. ! 516: L### Set the notelength parameter for all following notes which do not have ! 517: one specified (ie: override the quarter-note default) Leval note lengths ! 518: are 1-64 indicating the recibrical of the fraction (ie: 4 indicates a 1/4 ! 519: note). ! 520: < Move the the next lowest octave. ! 521: Octave cannot go above six or below zero. ! 522: > Move to the next highest octave. ! 523: Octave cannot go above six or below zero. ! 524: ! 525: The lowest playable character is C in octave zero. The frequencies for the ! 526: six C notes for the seven octaves in rising order are: ! 527: 65406, 130810, 261620, 523250, 1046500, 2093000, 4186000 ! 528: ! 529: Purists will note that the lower three octaves are not exactly one half of ! 530: the next higher octave in frequency. This is due to lost resolution of ! 531: low frequences. The notes *sound* correct to me. If anyone can give me ! 532: an excellent reason to change them (and more correct integer values for all ! 533: notes) I am willing to do that assuming the notes still sound "right". ! 534: ! 535: !!!PLEASE NOTE!!! If you are playing some ANSI Music then ask the user if they ! 536: heard it, ALWAYS follow it with an 0x0b 0x0a is the shift lock character which ! 537: *will* cause people with anything but an ANSI-BBS terminal (ie: *nix users using ! 538: the bundled telnet app) to have their screen messed up. 0x0b "undoes" the 0x0a.
