NAME    [Toc]    [Back]

     startmidi,	stopmidi - start MIDI daemon

SYNOPSIS    [Toc]    [Back]

     startmidi [-n name] [-s speed] [-p	proto]	-d /dev/tty{d,f}x

     stopmidi -d /dev/ttydx

     stopmidi -n name

     startmidi

DESCRIPTION    [Toc]    [Back]

     Startmidi initializes the serial ports and	links them to the MIDI streams
     driver.  startmidi	also reports the names of the MIDI interfaces
     currently configured.  stopmidi removes the specified interface.  The
     following options control the startmidi command:

     -n	name
	  Name of the interface.

     -d	device
	  The actual driver this interface will	talk to, either	a serial port
	  or internal.

     -p	proto
	  Specifies the	protocol used.	This parameter is optional, and
	  defaults to RS422 with an external clock (Macintosh (r) compatible
	  mode).  Possible values are rs232 for	RS232 communications, aso232
	  for RS232 on an ASO board, aso422 for	RS422 on and ASO board and
	  rs422	for externally clocked 422.

     -s	speed
	  The speed the	interface operates at, if not 31250 baud. Options are
	  9600,	19200, 31250, 38400, 115200 and	125000.	 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.

     Stopmidi shuts off	MIDI on	the specified device, or the interface
     specified by name.

     An	internal MIDI 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
     mdRegister(3dm).

     If	startmidi is killed, the devices linked	to the MIDI driver will	be
     unlinked, and applications	will cease to be able to send and receive
     MIDI.

NOTES    [Toc]    [Back]

     For the most part,	startmidi is used by the system	administration tools
     for port configuration.  This tool	is accessed through the	system manager
     menu selection in the desktop toolbox.  However, the system manager as
     yet has no	way of setting up internal MIDI	ports, so that must be done by
     hand.

     115200 baud rates are only	supported on the ASO board at this time.

     Cabling can be problematical for some combinations	of serial port and
     MIDI interface.  The manual page serial(7)	has the	pinouts	for all	SGI
     serial ports and may be helpful in	obtaining the necessary	cabling.
