4.12.1 Jdisint

Name: »disable interrupt« - Disable interrupts of the multi-functional peripheral port.
Opcode: 26
Syntax: void Jdisint( int16_t number );
Description: The XBIOS routine Jdisint disables a designated type of interrupt that is specified by number on the multi-functional peripheral port. The parameter number refers to the following interrupts:

number Description
 0 I/O-port bit 0 Busy parallel port
 1 RS-232 DCD
 2 RS-232 CTS
 3 Blitter
 4 Timer D, RS-232 Baud generator
 5 Timer C, 200 Hz system clock
 6 Keyboard and MIDI
 7 FDC and DMA
 8 Timer B line flyback
 9 RS-232 transmit error
10 RS-232 transmit buffer empty
11 RS-232 receive buffer full
12 RS-232 buffer full
13 Timer A
14 RS-232 RI
15 Monochrome monitor detect
Return value: The function does not return a result.
Availability: All TOS versions.
Group: Interrupt functions

4.12.2 Jenabint

Name: »enable interrupt« - Enable interrupts of the multi-functional peripheral port.
Opcode: 27
Syntax: void Jenabint( int16_t number );
Description: The XBIOS routine Jenabint re-enables a designated type of interrupt that is specified by number on the multi-functional peripheral port. The parameter number refers to the following interrupts:

 2 RS-232 CTS
 3 Blitter
 4 Timer D, RS-232 Baud generator
 5 Timer C, 200 Hz system clock

10 RS-232 transmit buffer empty
11 RS-232 receive buffer full
12 RS-232 buffer full
13 Timer A
14 RS-232 RI
15 Monochrome monitor detect
Return value: The function does not return a result.
