Comm API and LPT addresses

Question

HI!
I want to implement a little programe in Java.
The programme looks something like this in asm:
asm{
mov dx,37Ah
mov al,3
out dx,al
mov dx,378h
mov al,3
out dx,al
The main problame is that the getOutputStream() function is related to 378h (LPT's data address) and I want to write to 37Ah (LPT's controll address);
How could I write to the other 2 addresses?

Answer 1

outport is a function from Borland C++. So you'll have problems using such function.
You'll need to use _outp, check the reference in MSDN.
You'll also need to use the statement
#pragma intrinsic(_inp,_inpw,_inpd,_outp,_outpw,_outpd)immediately below including #include <conio.h>
This is an excerpt from MSDN.
int _outp( unsigned short port, int databyte );
unsigned short _outpw( unsigned short port, unsigned short dataword );
unsigned long _outpd( unsigned short port, unsigned long dataword );
Routine Required Header Compatibility
_outp  <conio.h>     Win 95
_outpw <conio.h>     Win 95
_outpd <conio.h>     Win 95
The outp, outpw, and _outpd functions write a byte, a word, and a double word, respectively, to the specified output port. The port argument can be any unsigned integer in the range 0 � 65,535; databyte can be any integer in the range 0 � 255; and dataword can be any value in the range of an integer, an unsigned short integer, and an unsigned long integer, respectively.
