2 Serial UART 16450/16550 MIDI driver
7 * 0 - Roland Soundcanvas support (default)
8 * 1 - Midiator MS-124T support (1)
9 * 2 - Midiator MS-124W S/A mode (2)
10 * 3 - MS-124W M/B mode support (3)
11 * 4 - Generic device with multiple input support (4)
13 For the Midiator MS-124W, you must set the physical M-S and A-B
17 (midiCnD0-midiCnD15).  Whenever you write to a different substream, the driver
19 number plus 1.  Roland modules use this command to switch between different
24 Usage example for simple serial converter:
28 	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 speed=115200
34 	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 outs=4
36 In MS-124T mode, one raw MIDI substream is supported (midiCnD0); the outs

41 Usage example for MS-124T, with A-B switch in A position:
45 	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=1 \
48 In MS-124W S/A mode, one raw MIDI substream is supported (midiCnD0);
56 	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=2
58 In MS-124W M/B mode, the driver supports 16 ALSA raw MIDI substreams;
60 number gives a bitmask of which MIDI Out connectors the data should be
73 	/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=3
75 The MS-124W hardware's M/A mode is currently not supported. This mode allows
82 Midiator models other than MS-124W and MS-124T are currently not supported.
83 Note that the suffix letter is significant; the MS-124 and MS-124B are not
84 compatible, nor are the other known models MS-101, MS-101B, MS-103, and MS-114.
86 but no units to experiment with.  The MS-124W support is tested with a real unit.
87 The MS-124T support is untested, but should work.
