_SSSS_tttt_aaaa_rrrr_tttt_mmmm_iiii_dddd_iiii initializes the serial ports and links them to the MIDI streams
driver. _ssss_tttt_aaaa_rrrr_tttt_mmmm_iiii_dddd_iiii also reports the names of the MIDI interfaces
currently configured. _ssss_tttt_oooo_pppp_mmmm_iiii_dddd_iiii removes the specified interface. The
following options control the _ssss_tttt_aaaa_rrrr_tttt_mmmm_iiii_dddd_iiii command:
_----_nnnn _nnnn_aaaa_mmmm_eeee
Name of the interface.
_----_dddd _dddd_eeee_vvvv_iiii_cccc_eeee
The actual driver this interface will talk to, either a serial port
or _iiii_nnnn_tttt_eeee_rrrr_nnnn_aaaa_llll.
_----_pppp _pppp_rrrr_oooo_tttt_oooo
Specifies the protocol used. This parameter is optional, and
defaults to RS422 with an external clock (Macintosh (r) compatible
mode). Possible values are _rrrr_ssss_2222_3333_2222 for RS232 communications, _aaaa_ssss_oooo_2222_3333_2222
for RS232 on an ASO board, _aaaa_ssss_oooo_4444_2222_2222 for RS422 on and ASO board and
_rrrr_ssss_4444_2222_2222 for externally clocked 422.

The speed the interface operates at, if not 31250 baud. Options are
_9999_6666_0000_0000, _1111_9999_2222_0000_0000, _3333_1111_2222_5555_0000, _3333_8888_4444_0000_0000, _1111_1111_5555_2222_0000_0000 and _1111_2222_5555_0000_0000_0000. This options allows
different sorts of interfaces to be connected to the machine. 38400
is normally used for connecting to a Key MIDIator. 125000 is used
by "high speed" Macintosh intefaces. 115200 is used by some PC
serial port interfaces.
With no parameters, startmidi prints a list of the available MIDI
interfaces.
SSSSttttooooppppmmmmiiiiddddiiii shuts off MIDI on the specified device, or the interface
specified by name.
An iiiinnnntttteeeerrrrnnnnaaaallll MMMMIIIIDDDDIIII device is specified by passing the string "internal" for
the -d parameter. Internal MIDI allows programs to use MIDI
communications and timing for interprocess communication. See
