Loading the Hook Code

In order to use Joy232 it is necessary to load it on the MSX by either of the methods presented below.

Method 1:

Copy the file "joy232.bin" to a floppy disk (or an equivalent option like the SD Mapper interface.

load and execute the program by typing

bload "joy232.bin",r

It will install the hook code.

Method 2:

Type the following program:

10 REM
20 REM Joy232 hook code
30 REM danjovic 2016
40 REM
50 EI=&HFAF5:SIZE=44
60 FOR A = EI TO EI+SIZE
70 READ B$: POKE A,VAL("&H"+B$)
80 NEXT A
90 REM
100 POKE &HFFB8,&HFA
110 POKE &HFFB7,&HF5
120 POKE &HFFB6,&HC3
130 REM
140 DATA F3,F5,C5,E5,6F,3E,0F,D3
150 DATA A0,26,FF,A7,CB,15,CB,14
160 DATA 06,0B,DB,A2,CB,87,CB,1C
170 DATA CB,1D,CE,00,D3,A1,0E,11
180 DATA 0D,20,FD,10,ED,E1,C1,F1
190 DATA A7,FB,33,33,C9

Execute the program to install the hook code.

run

If you typed the code it is recommended to save it for future usage. It can be done by either:

a) Saving the code to a floppy drive by typing

save "joy232.bas"

b) saving to cassete by typing

csave "joy232.bas"

Testing the hook code:

First connect the USB to Serial interface to the PC and do the wiring to the DB-9 connector as follows:

• Pin 9 from DB-9 to the GND of serial dongle
• Pin 6 from DB-9 to the serial input line. The serial Dongle I am using name this pin as TXD

Some serial dongls might have different pinouts and naming for the pins. The one I am using was wired as below:

Then connect the DB-9 female to MSX joystick port 1.

Then send something to the printer by simply typing any command which uses the printer, forinstance:

lprint "Hello World"
