==================== Функция 20 - интерфейс MIDI. ====================

Параметры:

-------------------- Подфункция 2 - вывести байт ---------------------
Параметры:
* eax = 20 - номер функции
* ebx = 2 - номер подфункции
* cl = байт для вывода
Возвращаемое значение (одинаково для обеих подфункций):
* eax = 0 - успешно
* eax = 1 - не определён базовый порт
Замечания:
* Предварительно должен быть определён базовый порт вызовом
подфункции 1 функции 21.

!!! ВНИМАНИЕ. Данный интерфейс устарел и не должен использоваться !!!
Параметры:
* eax = 21 - номер функции
* ebx = 1 - номер подфункции
* ecx = номер базового порта
Возвращаемое значение:
* eax = 0 - успешно
* eax = -1 - ошибочный номер порта
Замечания:
* Номер порта должен удовлетворять условиям 0x100<=ecx<=0xFFFF.
* Установка базы нужна для работы функции 20.
* Получить установленный базовый порт можно вызовом
подфункции 1 функции 26.

==================== Function 20 - MIDI interface. ===================
======================================================================
!!! WARNING. This interface is outdated and should not be used !!!
----------------------- Subfunction 1 - reset ------------------------
Parameters:
* eax = 20 - function number
* ebx = 1 - subfunction number
-------------------- Subfunction 2 - output byte ---------------------
Parameters:
* eax = 20 - function number
* ebx = 2 - subfunction number
* cl = byte for output
Returned value (is the same for both subfunctions):
* eax = 0 - success
* eax = 1 - base port is not defined
Remarks:
* Previously the base port must be defined by
subfunction 1 of function 21.

!!! WARNING. This interface is outdated and should not be used !!!
Parameters:
* eax = 21 - function number
* ebx = 1 - subfunction number
* ecx = number of base port
Returned value
* eax = 0 - success
* eax = -1 - erratic number of a port
Remarks:
* Number of a port must satisfy to conditions 0x100<=ecx<=0xFFFF.
* The installation of base is necessary for function 20.
* To get base port use subfunction 1 of function 26.
