You can't access the bios routines from windows>98

EDIT: Using the serial port in windows from C is similar to using any other file (see http://msdn.microsoft.com/en-us/library/ms810467.aspx) if you need detailed low level control of individual CTRL lines it's a bit trickier but still doable.

Configuring a serial port and transmitting data over it is built into the .NET framework. Check out the System.IO.Ports.SerialPort class documentation, there are some examples to get you started.
