RS-485 is an EIA standard for data communication, so I am not exactly sure
what you mean by "a rs485 port". Generally speaking, you can read I/O ports
on 0x86 based machines by using the C standard library function, "inp". Note
that you cannot use this approach for Windows NT based machines (i.e., NT4,
Win2K, WinXP) because they do not allow direct port access in user mode.
For those OS's you will need to write a device driver to access ports.

Hope this helps,
Brian
