Accessing ports

[kajdan]

Hello

I am using the free Borland compiler.

However I cannot find how to access I/O ports. For some reason, pin and
pout are not available. How can I achieve this?

I also tried with inline assembler, but the compiler doesn't support it
(no tasm32.exe).

Is there another other free MS-DOS based compiler that will do this?

Thanks

You're likely to get better answers in another newsgroup, perhaps
comp.os.msdos.programmer.

Wasn't it inp/outp or inb/outb or something? Possible different
functions for different word lengths also..

inb/outb and inw/outw on Linux/x86, among others for various bitlengths.
But there doesn't seem to be any sort of standard for it so it probably
varies by OS, by hardware and by compiler suite.

In Turbo C++ (a compiler by Borland which includes a C compiler) there
are inp, inport, inportb, outp, outport and outportb. Your compiler
may have some or all of these.

Failing that, try comp.os.msdos.programmer as Keith has suggested.
