- There are numerous ways of initializing a serial port with 'C'. My standard
- method is to directly write to the UART addresses. A more commonly used method
- is to use a library function such as `_bios_serialcom`. Most `C` compilers for
- DOS have this function or one that is similar. If you wish to write directly
- to the port addresses, the proper function to use would be 'outp','outport`,
- `outportb', etc., again depending on the compiler you are using.
- Good Hunting...
