This archive has a device driver for the Jay Kubicky BYTE
article midi board.  The driver is installed by putting MIDI.BIN in your
boot disk root directory, adding a line to your CONFIG.SYS file
DEVICE=MIDI.BIN
and then re-booting.  This version assumes that both UARTs are hooked up
with separate inputs and outputs, but if you stick to device MIDIA (midi
port A), it will work on an unchanged board.

        Included are two C programs that demonstrate how to use the
driver, TWRITE MIDIA will ask you for hex values to send down the MIDIA
device.  It's dumb:  you must type them one at a time with a carriage
return after each.  Try 90 40 40 40 0 to hear it make a noise.
TREAD MIDIA will display hex bytes that it gets from the MIDIA device.
You can select a timeout delay period in microseconds (2000 or more is
a good first value).  If you do not type anything on the midi keyboard
within that time, a beep and an error display is printed.  Overflowing
the input buffer will also print a different message.  (Overflow only
happens because the C compiler is terribly slow at printing hex numbers,
and pitchbend and aftertouch are FAST!).  Note that both programs
require that you mention the name of the midi device when you run them
so they know which one to test. If you haven't hooked up the 2nd uart,
always say MIDIA   

        The driver, and both test programs are included in source and
executable.  MIDI.ASM is the device driver, and MIDIO.ASM is some
C-callable routines to get raw-mode access to MSDOS devices.  This
version assumes Microsoft C with the small memory model.
