c++ - Need help with bios.h

reply Paul Apostolik <parabolis softhome.net> writes:
    I have tried to figure this out and have had no luck. I want be able
to read from and write to the serial and parallel ports. I have not been
able to use anything in bios.h yet. I keep getting a message that the
function has not prototype:

/*  Example for _bios_serialcom  */

#include <bios.h>
#include <iostream.h>

void main() {
 unsigned com1_status;

 com1_status = _bios_serialcom (3,0,0);
 cout<<" Com1 status : "<<com1_status<<endl;
}

The exact error is : Error: function '_bios_serialcom' has no prototype

Here is what the compiler sees of bios.h :
----------------------------------------------------------------
/* Copyright (C) 1986-2001 by Digital Mars. $Revision: 1.1.1.1 $ */
#if 0x823  || __RCC__
#pragma once
#endif

#ifndef __BIOS_H
#define __BIOS_H 1

#ifndef __NT__
#endif /* __NT__ */

#endif
----------------------------------------------------------------

Any suggestions? Thanks!

    It worked! Thank you. I must ask why I needed to use a large memory model
though? Thanks again!
