Parallel PCI Port in Dosemu

Parallel PCI Port in Dosemu

[Slawomir Wawak]

Hello,
I use under dosemu application which needs hardware key attached to parallel 
port. It was ok, while I've had computer with parallel port on the 
motherboard.

New motherboards have no parralel port, so I plugged port on PCI card. Linux 
and Dosemu can see this port, but my application can't. Port on PCI has 
ioports EC00-EC02, not 378-37f. Application tries to communicate always in 
378-37f range. 

My question: Is it possible to remap ioports? Can dosemu translate questions 
sent to port 378 to EC00? 

Thanks.
Regards, Slawomir Wawak.

You must set your lpt port addres for LPTx name. Use following program:

#include <stdio.h>

void setlpt(unsigned int num, unsigned int port)
{
        unsigned int _offset;

        if ((num == 0) || (num > 4))
                return;

        _offset = 6 + (num * 2);

        printf("Setting LPT%d to 0x%X\n", num, port);

        asm {
                mov ax,0x0040
                mov es,ax
                mov di,_offset
                mov ax,port
                stosw
        };
}   

int main ()
{
        setlpt(1, 0xEC00); //set LPT1 to be at 0xEC00
        return 0;
}
